Peaches

Peaches is a large, yellow-eyed, green monster, possibly an ogre, that aids Momon in slapping her sons Waltazar, Larius and Ignus, and fighting in wars. He owns a big flail, which, instead of an iron ball, has a huge glove at its end.

Trivia

 * Down in the dungeon just Peaches and me, a lyric in the song  by, is probably the origin of his name.
