Croc: legend of the Gobbos
The game was originally created as a game with Yoshi, a character from Nintendo's Super Mario series of video games. However, Nintendo did not allow the creators to use the character, so a brand new character was created instead.  Croc: Legend of the Gobbos sold well, and was a success for Argonaut. A second game was made in 1999, called Croc 2.
