E.T. is a extrasensory minor character in Abobo's Big Adventure.
E.T. is a alien from the 1982 film called "E.T. the Extra-Terrestrial". But had a very infamous video-game on the Atari 2600 by Atari, Inc. with the same name from the film. This game is often considered to be one of the worst video games of all time. The game also became a very big commercial failure, and one of the main causes of the "Video game crash of 1983".
In The Game
E.T. makes a small cameo in the game in the level Contrabobo, when he comes from the mouth of Kirby, when he vomits after his boss battle is over. E.T. is one of few non NES characters to appear in the game.
