One morning, Flint will visit you to give you the Barn Blueprint. This can happen from the start of Week 2, but may be later, depend if you have other prioritised cut scenes that trigger (e.g. Mayor visiting for completing the 13 residents quest)

The barn can house up to 4 blobs, and requires 50 wood and 50 fibre.


The Blob Barn (Big) Blueprint can be purchased directly from Flint, at a cost of 15,000 coins!


This big barn can house up to 8 blobs, and requires 100 stone, 100 wood, and 5 ingots (Iron) to build

To build the barns, click on the Workbench in your farm, select the blueprint, and place the barn in your farm.

Tip: to make space, you can select items like Trees, Logs, Bushes and Stones and move them around, so you do not need to clear the farm manually to make space for your barns.

Note that you can build multiple barns of the same type!

After you build your first barn, entering the barn will trigger an event with Jade and Clara. Jade will give you a free Cow blob egg and will guide you on how to hatch the egg, use the feeders and care for your blobs.

To start breeding, you will need to get at least 2 heart fruit. Flint sells Heart Fruit as 25 coin each, and you can find Flint in different places around the map during the week, but not during the festival.

Later in the game, you will also be able to buy a Heart Fruit tree from Emerald, where you can grow your own Heart Fruits.


To start breeding, you will need to place two blobs inside a barn. Then, using the Blob Interaction button, feed both blobs a Heart Fruit. (You can also leave two Heart Fruit in the feeder, but if you have more than 2 blobs, you may get unexpected result)

A heart icon will show at the top of each blob. You can now leave the barn and go to sleep.


Next day, you can enter the barn and see that they have an egg icon, with 1/3 indicator. This will increase one each day.

After the fourth sleep, when entering the barn you will find an Egg (Brood).

You can hatch the egg in any barn where you have room, or sell it for 400 coins.


If you decide to give a fruit heart to 4 or more blobs in the same barn, then, you will not be able to control the breeding pairs.

After you sleep, head into the barn and see that there are two random couples. If you need specific pairs, only start one pair of breeding per day. Once that breeding is making an egg on the following day, then you can go ahead and start breeding another pair.

What often makes brood blobs stronger is the chance for Mutations.



A blob can obtain up to three mutations. Each mutation makes the blob immune to a status effect:

• Skullmakes blob immune to poison
  
• Spiral makes blob immune to confusion
  
• Zzz makes blob immune to sleep
  
• ... message makes blob immune to silence
  
• Eye (with an x) makes blob immune to blind

You can increase the chance for mutations by obtaining the Breeding (Mutations) skill

Blobs can have abilities, which are either passive, like Produce Milk, or active, like the Turtle Blob's Sprinkler.

These abilities can be passed down through breeding. Note that the brood blob can only have one ability. That said, you can have a barn full of different blobs that can use sprinkler and water your barn!


When breeding blobs, the brood will inherit skills from the parents.

This is mostly randomised, which means you have little control over the results. However, there are a few things to keep in mind.


A blob can only inherit skills that are typeless or of a matching type. For example, if I breed a Bee blob (which is forest) and a pig blob (which is magma), if the brood egg is a magma-type, it cannot receive the Skills "Bee Rage" or "Flower Field", since they have conflicting elements.

Breeding two forest-types together would therefore increase the chance that the hatch can receive such skills.
Similarly, if you are breeding a blob that only has forest-type skills with a blob that only has magma-type skills, then the blob will only obtain skills from the parent of the matching type and will not learn new skills.



I personally suggest aiming for breeding down 4 skills which have a mix & match of the following:

• A skill with sword (attack)
  
• A skill with clock (stopwatch)
  
• A skill with shield (defence)
  
• A skill with an AoE (double person).

The different icons are important as when that skill reaches 100%, it will increase the blob's stat by that power. Having the three different icons mean that you are able to level up all stats for that blob.

Having an AoE (area of effect, or multi-blob attack) is a powerful way to be able to clear 3 v 3 battles, and I really value that.

In the earlier screenshot, you can also see that my brood has both elemental and non-elemental attacks, as well as a status effect (Distract). There is no one optimal skillset, but you can find different combinations that will guide your way to Blobdom!

When you hatch an egg, the brood blob will often have a base stats that seems to be around the average current stats of the parents. This is not always the case.

One key factor is happiness. When hatching the egg, you may notice a % of happiness indicated right away.

The happier the resulting egg, the likelier it will have better base stats. On the contrary, an egg with lower happiness will have less base powers. That is how I managed to breed a base blob with 12 base power... oops!


To increase blob happiness, you must consider five factors: decorations, temperature, cleanliness, interactions (heart icon), and hidden values.




The flower icon indicates the barn's decoration value. In the barn workbench, choose items with decoration icons.

To reach the maximum decoration value in a barn, you will need a total of 10 decorations.

The easiest way to fulfill this is to buy the Painted Eggs blueprint in the Painted Eggs festival, and then place 10 painted eggs in one barn.



The second icon represents temperature. This one is trickier as different blobs have different preferences. Therefore, you may have to do trial and error to figure out what is the ideal preference for your blobs.

Using the Blob Registry in the Barn, you can check the barn temperature.


This is determined by two factors:

Temperature Equipment

Placing an Air Conditioner or a Heater will reduce or increase the temperature of the barn. You can purchase their blueprints from Flint.

After placing an air conditioner or heater, you can remove them by hovering over them and clicking "Store In". This will place the item back in a hidden inventory, and next time you try to build one, it will automatically use the one in storage, rather than use new materials.

Change of Seasons

The second factor is seasons. During Solis, barns are typically more warm, whereas during Frigus, the temperature drops.

Based on a couple of tests I did, it is best to add or remove temperature equipment on Week 3 - Festival Day, the night before the new season arrives. From my testing, it looks like the happiness factored in after the season/temperature change, although this may potentially change in future updates.


If you've fed your blobs, you will know that they leave a stinky poo the next morning. Make sure to pick up the popo using a shovel every day to improve the cleanliness.

Eventually, you should consider building a litter box, but keep in mind that you still need to collect the poop to make room for more poop.

The final icon is represented by the heart symbol. This looks to be the most straightforward: interact with the blob and pet it to increase this value.

There may be hidden values, however I don't have information on how they impact the happiness. Please note that these are mostly speculation and observations.

Happiness History

First of all, I believe that there may be an impact on the history of the blob's happiness throughout the breeding process. Disregarding a blob for all days and only taking care of it on the final day of egg-making does not fully restore its happiness.

However if you start caring for a blob on the first day you give hearts, it seems to be able to go up to maximum happiness throughout one breeding process.

Food and Cravings
In each barn, you have feeders to place food for your blobs. Although there is not an icon that represents this, leaving your blobs to starve seems to negatively impact the happiness.

It's ideal that you leave food for all your blobs every day. In addition, if you leave a food that is being craved, you will further increase happiness, apart from gaining the Max HP benefit.
I was able to achieve 98% happiness by attempting to fulfil cravings (including play) every day.

Blobs inherit features from their parents. This is much harder to describe due to the number of combinations, however, here's a short list of blob features that are passed down by breeding:

Each blob has three colours. It looks like some blobs, like the pig, may have hidden colours that can be inherited.

Each colour is inherited separately, so a blob may inherit primary colour from Parent 1, and secondary and tertiary colour from Parent 2.

Primary colours are often visible in the main blob (e.g. the pig is pink), whereas secondary and tertiary colours are shown in additional features, such as shading in the bunny ears, or the pink in the bat wings.


Blobs can pass down physical features, such as face, ears, wings, tails, and face markings. There are also other variations, including blob size and shape (I'm not quite sure how the poop blob breeds).

Most of these are randomised between the two parents and are not guaranteed.



For example, if Parent A has Bee Antannea and Parent B has Fox's ears, the blob can have either the Antannea, the ears, or no ears!


However, it looks like that if both parents share the same feature, this will be guaranteed towards the brood.


If you obtain a brood that is closer to what you want but not 100% what you need, it often makes more sense to breed this with one of the original pair, rather than start from scratch.

Each egg is generated when you go to sleep on the 4th night, before the game auto-saves.

If you have the egg and you don't like, reloading the latest auto save file will yield the same result.

Therefore, before going to sleep, you can do a manual save, and sleep. If you want to reroll the egg, load the manual save, sleep again, and hatch. Repeat until you are satisfied with the egg
