Somewhere in the desert lies the Wolf Zirkus: a strange circus where Popee, a clown in a pink rabbit jumpsuit, shares the stage with Kedamono, a purple creature who wears a mask. Together, they juggle the whims of performing, practicing their acts, and poking fun at each other. In a world where anything seems possible, there is no telling what will happen next during this eccentric spectacle.

Popee the Performer's 11th episode was banned from being rebroadcast on Kids Station in Japan due to complaints about excessive violence in a children's show. A related concern led to episode 27 being released only on DVD.
