This Magik Moment!

Sophocles is on a TV quiz show, so Ash and the gang come to the station to cheer him on. While there, they see the filming of a series starring a Magikarp; however, the Magikarp seems to have something wrong with it. On another TV show, the regular actresses don't show up in time, which leads to Lana, Mallow and Lillie being cast as replacements.
