In the cafe their is the goat feeding mini-game. If you play the goat feeding mini-game enough the goat will eventually level up. Every time the goats levels up 10 levels you get what is called a mascot. Their mascot serve little to no purpose other than adding a new loading icon to the mix and telling you what each character likes and dislikes about the mascot you got. The mascots you get are of characters you met somewhere else in the game. Below is a list of the mascots you can acquire. Right now this list is incomplete but with grow over time. You can access a screen showing what mascots you have acquired by talking to the curator near the museum in the cafe.
