Giant Billy and Mandy All Out Attack (S06E07)

Eager to enjoy classic giant monster films, Billy and Irwin are whisked away by Grim to Japan, where they encounter real-life creatures. They soon find themselves in the midst of an epic clash between Cragorah, a turtle-like beast reminiscent of Gamera, and the three-headed feline menace, Kittirah, echoing Ghidorah. To aid Cragorah, Grim gives Billy a monstrous transformation, turning him into a giant hero akin to Ultraman. Just then, Mandy arrives, furious at their unauthorized adventure. Commanding the formidable Mecha-Gorillasaur, she triumphs over Kittirah and teaches Billy a lesson.
