Fatty Bear's Birthday Surprise is the second video game made by Humongous Entertainment (the first being Putt-Putt Joins the Parade) and the first and only of the Fatty Bear point and click adventure games, though the character was also used in the mini-game compilation Fatty Bear's Fun Pack and the crossover spinoff Putt-Putt & Fatty Bear's Activity Pack, which was a combination of the previous game as well as a similar game featuring HE's character Putt-Putt. It was released in 1993 on both floppy disks and CD-ROM for DOS and Macintosh as well as the 3DO Interactive Multiplayer. The game was later re-released in 1995 and contained a Windows/Mac/DOS-compatible disc.
