Accounting+ Secret/Hidden Zoo Level
To get to the secret zoo level, you gotta burn the bench in the waterpark level. This is hinted at by the space cleaner if you listen to her dialogue very carefully. The dialogue is randomized, so you might need to come back to her a few times to hear this. Her last line is: “I will burn the bench for you!”. Another tip is that the radio on top of the bench says: “Waterproof radio”.
So, first, play the correct zoo music on the space-level animal piano. You learn this code in the first tree level by throwing objects out of bounds. The correct sequence is:
SHEEP-CAT-DUCK-DOG. (This is a reference to the Garfield movie, which points to how all the above-mentioned animals are not CG except Garfield. You learn this in the alley level if you pirate the Garfield film.)
Then fix the copy machine, play through the game, and don’t forget to plant/ leave the seed from the treehouse in the tree level in the pot and proceed through the game like usual.
When you reach the fire forest stage hold to the burning log/ VR display and don’t let go until you go all the way through the game again to the point where you can eat a yellow pill, eat the pill, and teleport to the waterpark. Then just burn the bench with the burning log/ VR headset.
