Fatty Bear's Birthday Surprise[]
Fatty Bear can play this mini-game in the living room. There are mostly clickables in the aquarium.
In some games, the puppy may hide the letter "A" for the "Happy Birthday" sign in the aquarium. The "A" needs to be clicked in order for Fatty Bear to fish it out and obtain it.
