Lionel wakes up one morning, much like he does every day, to find that overnight, he's grown a pair of antlers on his head! To help him feel better, Cleo reads him the book ""Imogene's Antlers"" - also about a kid who woke up one morning to find she had grown antlers. When Lionel is still feeling low, his parents try to come up with helpful ""uses"" for his antlers.
