In 1995, Yoshi had his moment. The character’s Super Mario World debut was so strong, Nintendo handed the dinosaur sidekick his own sequel. A surprise divergence from the Mario franchise found the character escorting a baby version of the plumber in search of his kidnapped twin.

Super Mario World 2: Yoshi’s Island was regarded as an instant classic for the Super Nintendo. The positive reaction was due, in part, to some bold aesthetic choices. The game featured a shaky line style, both in keeping with the playful infant motif and to further highlight that the title wasn’t just another Mario game.
