“How serendipitous! Mysterious creatures are the subjects of my very pages... but I cannot access any of that information myself.”

—Mr. E, Yoshi and the Mysterious Book

Mister Encyclopedia, who goes by the shortened name Mr. E, is a character in Yoshi and the Mysterious Book. He is a large encyclopedia with eyes and a white mustache on his cover. He contains information on many unusual creatures, although he is unable to read his own pages. He falls from the sky onto an island that has Yoshis. Yoshi jumps into Mr. E's pages to help Mr. E by learning about the creatures. It appears that the game's levels occur within Mr. E's pages.

Naming

"Mr. E" is a homophone of "mystery", the meaning of his original Japanese name. This alias is shared with two unrelated characters from previous games, one from Paper Mario and one from Mario Party Advance.
