Fatty Bear's Birthday Surprise is a 1993 adventure video game developed by Humongous Entertainment.
A girl named Kayla falls asleep the night before her birthday, looking forward to a big surprise present that her parents announced.
Fatty Bear and Matilda Rabbit then head to the kitchen in order to start making the cake.
After baking the cake for the party and returning the missing letters, Fatty Bear jumps onto Kayla's bed and goes back to stuffed animal form as morning comes.
Kayla appreciates her birthday party and thanks everyone for it, especially Fatty Bear, to whom she gives a big hug, ending the game.
