Mirror Mirror, Off the Wall - S1.E20

The Mon Colle Knights rescue Kahimi from a group of Dobe Rats. Prince Eccentro finds a mirror thinking that it's a Monster Item and it transforms him into some character from a TV Show that Ms. Loon watches. He also uses it to keep Kahimi laughing, make Professor Hiragi a cleaning person, and something else to Rockna. When Eccentro sics a Sand Worm on the Knights, the mirror breaks and the Mon Colle Knights merge with Kahimi and and return the Sand Worm into the Dobe Rats that were turned into it via the mirror. The mirror was later revealed not to be a Monster Item. Meanwhile, Gabriolis defeats a giant and steals an orb which'll become a part of his plan to destroy the Mon Colle Knights.
