|This article is about a/an episode in Mighty Morphin Power Rangers.|
Trini is learning a new style of Kung Fu. Meanwhile, Rita sends down the mighty Mantis monster to challenge and test Trini's new skills, as she is impressed with them. Somewhat impressed but still thinking that Trini's enthusiasm is "dorky" (as usual), Bulk and Skull attempt to create their own Kung Fu style: Cockroach Kung Fu. In the process, however, they are humiliated by everyone else.
