Kappa Mikey - Season 2 Episode 19 Seven LilyMu

Like the heroes of the famous Japanese film The Seven Samurai, the cast responds to a distress call from a poor boy and LilyMu fan named Riku, whose playground is about to be destroyed by an evil Garbage Man to make way for a landfill. However, used to doing live shows, the five are under the impression that this is just another gig, and Riku thinks they are real heroes instead of actors.
