--Mama Luigi, correcting Mario.
Mama Luigi is that strange guy who's both male and female.
When Mama Luigi found a yoshi egg, it hatched, and in it was Yoshi. Right then, Yoshi claimed Mama Luigi as his mama.
When Yoshi wanted a bedtime story, Mama Luigi gave him one. He told Yoshi how Mama Lugi found him.
For some reason, Luigi wheezes a lot. He never stops correcting Mario, and he talks nonstop about how he saved Yoshi.
