A big bouncy bunny. Mr. Herriman is a proper imaginary friend who adores rules, and doesn't tolerate rule breaking or bad behavior. He was imagined by Madame Foster (Founder of Foster's Home) she imagined him at a young age and still hasn't given up on him. Mr. Herriman has a rather large carrot addiction as he loves eating them. In fact he gets paid in carrots. Mr. Herriman may seem stuck up here and there, but we all know he's just big funny bunny.
