Intro
So, you really want that sweet YouTuber merch, ayy? Well, you've come to the right place!
Jack's Septic Tank
To get this unique item, you need to go to the "Settings" menu from the title screen (Don't worry, this won't involve hacking the game or anything!). Then, select "Redeem a Key" and copy the code below:
SMHB-VC57-V748-8EGU-1EO
Now you can craft Jack's Septic Tank in any file! (Note: Only works on PC.)
The Unusual Doll (Markiplier)
Mark's item, unlike Jacks, does not need a code. In fact, he's just in a lifepod! Lifepod 7, to be exact.Because this lifepod's co-ordinants are corrupted, you need to do a bit of searching. However, the easiest and least dangerous way is to start at your lifepod and head directly south on the compass.

You should eventually come across the crag field biome:
You need to go past the first sort of "mountain" of rock, and look behind the second one you come across. Lifepod 7 should be there.

Just look inside, and there he is, Markiplier himself! (Note: You need to scan him for blueprints, you can't pick him up.)
Random Trivia!
1. Both dolls say lines from Jack and Mark's early access playthroughs!
2. Jacks doll, when it first came out, was a code only 1000 people could get. However, with the full release, everyone can get it!
3. Mark's bobblehead also plays his outro!
Note: Both items require 1 titanium and one glass to make.

There is a mod that adds it back just install it and it will stay vanilla just with the septic tank, you are welcome.

It is still part of the Decorations mod, though.

Sadly this is no longer avalible. Only 1000 people could get this with the cod and now it's removed for everyone else. :(

Lifepod 7 is approx 1006m directly south of your Lifepod, and about 177m deep.

WARNING! Carry on reading! Or you will die, even if you only looked at the word warning! Once there was a little boy called Joey, he was ten-years-old and he lived in a mental hospital because he posted a shitty copypasta onto a People Playground mod's comment section. He got so bad he went to kill all the staff in the hospital so the Feds decided that best idea was to get rid of him so they set up a special room to kill him, as inhumane as possible. And he sat there in agony for hours until he died. Now every week on the day of his death he returns to the person that reads this letter, on a monday night at 12:00 a.m. He creeps into your room and kills you slowly, by pegging you and watching you bleed to death. Now send this to ten other profiles on this one site, and he will haunt someone else who doesn't. This isn't fake. apparently if u copy and paste this to ten comments in the next ten minutes nothing will happen
