"Keel!" - Croc practicing to kill Zebra
The Doberman (or "Keeler") was doberman that was trained to kill Zebra. But since a croc was dressed up as a zebra he killed the croc instead. To which another croc said "Unkeel." The Doberman was abandoned from Zeeba Zeeba Eata, just like Snuffles, and was never seen again. He appeared in Because Sometimes You Just Gotta Draw A Cover With Your Left Hand. He was a One-Time-Comic character.
