A Boy and His Blob: Trouble on Blobolonia

A Boy and His Blob: Trouble on Blobolonia is a platform-puzzle game that puts the player in control of the boy; its gameplay revolves around feeding his blob companion different flavored jelly beans to change its shape into various tools in order to overcome obstacles and traverse the game's world. A Boy and His Blob was designed and programmed by David Crane. Licensed by Nintendo in the summer of 1989, development began and was completed in an intense six-week period. Crane has described the game's overall concept of a boy accompanied by a morphing blob as unconventional and wanted to try his own hand at implementing useful tools for the player.
