The Gwark is the World's Strangest Beast twice as big as a Jark,with eyes like a mouse, but wings like a Lark. It lives on the Isle of Ma-Trarck and eats Sassafras trees and Buble-nut bark! He comes from the Redbook Version of If I Ran the Zoo. In that version Gerald McGrew wants to catch it with a butterfly net!
Trivia[]
In the real book he changes into the Fizza-ma-Wizza-ma-Dill, and his name changes to the Island of Guark, the place where the Fizza lives.
