Giant Billy and Mandy All Out Attack

When Billy and Irwin want to watch classic giant monsters movies, Grim decides to take them to Japan to see real monsters. They meet the turtle-like Cragorah (a parody of Gamera) who engages in a fierce battle with the three-headed Kittirah (a cat version of Ghidorah). To help Cragorah, Grim transforms Billy into a giant monster too (a parody of Ultraman). Mandy soon arrives with the intent of punishing them all for organizing this expedition without her permission. Controlling Mecha-Gorillasaur (a giant gorilla robot) she defeats Kittirah and beats Billy.
