Little Johnny or simply Johnny is a young aardvark in Ice Age: Dawn of the Dinosaurs that had run into Sid's three baby Tyrannosaurs, one of the baby dinosaurs eating him whole. Johnny's mother demanded that Sid, who was only one that could stop the baby Tyrannosaur, call the dinosaur off from eating her son. Johnny was not found just then; instead a young Gastornis was brought out (her name is Madison). When Manny and Ellie arrived, Eggbert got scared and immediately puked out a dizzy Johnny.
