The Super Happy Party Bears become mentors when they meet Butter, a groovy caterpillar who’s got moves. This jitterbug can breakdance, tango, and boogie-woogie. The bears teach Butter everything they know, and he becomes a Super Happy Party Caterpillar dedicated to spreading the party spirit! When Butter mysteriously disappears, the bears frantically search for him, only to discover that the Jitterbug has morphed into a beautiful butterfly! The bears must accept that the Jitterbug has grown up and must follow his own fluttery path.
