The series is set around young clowns from Happytown, whose goal is to spread happiness and imbue positive mental attitudes around the world wherever they go. The young clowns are Big Top (the leader), Badum-Bump (Big Top's little brother), Hiccup, Tickles, Pranky, Blooper (Hiccup's big brother), along with their pet elephant, Rover, and their mentor, Mr. Pickleherring. The only thing that stands in their way is Awful BeBad, the master of doom and gloom, and his two minions, Geek and Whiner.
