The Gump is a character from the Oz Books series by L. Frank Baum. The Gump makes his first appearance in The Marvelous Land of Oz.
Gumps appear to be common animals in the land of Oz. They are elk-like creatures but with caprine whiskers. Specifically The Gump is actually just the head of one of these creatures mounted on a plaque, with two sofas for a body, palm tree limbs for wings, and a broom for a tail. This was all tied together with clothes line.
After his construction, the Gump was brought to life using the Powder of Life. He was later disassembled, at his own request, and remained only a head for the remainder of the series. The Gump is the only creature who was once living and then brought back to life by the Powder of Life.
