ToeJam & Earl is an action game developed by Johnson Voorsanger Productions and published by Sega for the Sega Mega Drive (Genesis) console. Released in 1991, it centers on ToeJam and Earl—alien rappers who have crash-landed on Earth. As they attempt to escape the planet, players assume the role of either character and collect pieces of their wrecked spacecraft. It references and parodies 1980s and early 90s urban culture and is set to a funk soundtrack. ToeJam & Earl's design was heavily influenced by the role-playing video game Rogue (1980) and derived various features from the game, such as the random generation of levels and items. As such, ToeJam & Earl is often considered to be an example of a roguelike game.
