Yoshi is a minor character in the SuperMarioLogan series. He is a green dinosaur that likes to repeat his name, but can speak English. He is attached to Mama Luigi and he eats all of SuperMarioLogan's bad games, and all of Mario's mushrooms. Black Yoshi is Yoshi's cousin. He's voiced by Logan, and formerly Luke. His most recent appearance is in Black Yoshi's Girlfriend Problem!.
He was also an antagonist in Mario and Luigi's Stupid and Dumb Adventures but he later reforms and becomes friends with Mario and Mama Luigi.
Yoshi has an odd personality. In videos after the debut of Mama Luigi, Yoshi lost almost all personality. However, earlier in "Season 0" of SuperMarioLogan, Yoshi plays a major role, revealing aspects of his personality.
Yoshi is Mario's deadbeat friend with a strange eating obsession. Yoshi eats almost anything, with no limits, whether it is food or Mario's collector's coin. Yoshi also is willing to commit crimes, like committing tax fraud and such as when he doesn't pay and dashes at McDonald's in Yoshi Takes Mario to McDonald's. Despite this, when he does something wrong he feels regret and attempts to make up for it, such as when he takes Mario to McDonald's after eating his collector's coin.
- It is unknown if Yoshi would return to the series. It is, however, possible that he might return in The SuperMarioLogan Movie!
