snake enemies. A Boy and His Blob is not a side-scrolling game, but presents the player with a series of interconnected screens. The player-controlled boy is limited to running left or right. The player cannot jump or swim, and if the boy falls too long of a distance, he dies on impact. Though the player directly controls the boy, Blobert is controlled by the computer AI. The player must rely on the shapeshifting blob to cross gaps, reach higher platforms, and overcome the obstacles and enemies. Blobert can change into several different tools when the player feeds him flavored jelly beans. A licorice jelly bean, for instance, will change Blobert into a ladder, while an apple jelly bean will turn him into a jack. Whistling at Blobert causes him to revert to his original shape and continue following the boy. The player is encouraged to experiment with the jelly beans and their effects to navigate the puzzling game world. Scattered throughout Earth's caverns are various treasures and diamonds that increase the player's score and can be used to purchase vitamins at a drugstore located within the game world. Vitamins can be used in conjunction with a special "VitaBlaster" gun, which is in turn used on Blobolonia to complete certain tasks. Also found on the map are extra jelly beans and peppermints, which increase the player's lives. Plot The game focuses on a teenage-looking boy discovering a Blob who needs help freeing his planet Blobolonia from the clutches of the evil emperor. On their way, the teenage boy discovered that the Blob can shape-shift when it eats certain jellybeans. He and the Blob partner up to stop the evil emperor. Development A Boy and His Blob: Trouble on Blobolonia was developed by Imagineering, the in-house developer of Absolute Entertainment. The game was chiefly designed and programmed by David Crane with help from his former Activision colleague Garry Kitchen. Kitchen was the president of the Activision spin-off company Absolute, which began self-publishing in 1988; Crane joined Kitchen at Absolute around the same time. Crane described the concept of a boy accompanied by a shapeshifting blob as "an off-the-wall idea". Crane stated that Blobert's design was heavily influenced by the characters Gloop and Gleep from the Hanna-Barbera cartoon The Herculoids. In terms of gameplay, Crane's goal was to advance the adventure genre as he had done with the Atari 2600 game Pitfall!. Since
