the toki tori logo: go back to the start of the game( Bottom left corner of the map, the second landing signal), then go right, the logo will appear.

If you (like me) get stuck in the incredible situation that you collected all the collectibles before you took a picture of one for your TokiDex:

In the house/room where you found/find the wings is a part of a collectible looking out of a drawer. You can take a picture of that, it counts as a collectible for the TokiDex.

It is possible to get back to the toki tori 2+ logo. There is an obelisk on to the left of it before the oil spill that blocks it off from the right side.

I'm only missing TOKI TORI 2+-picture, is this locked forever now?
There's also an oil spill in the beach with all the frogs by the stairs if you need to take picture of it.
