Extermes Dinosaures s01e41
Titre original : Surfasaur's Up!
The Raptors stage a phony costumed surfing contest to lure the Extreme Ones into a trap. As soon as the Dinosaurs are in the water, Spittor uses his sonic disruptors to create a massive tsunami - "the Big Kahuna of waves" - to wash them away so there'll be no one to stop the Raptors from setting off every volcano in the Pacific! The Dinosaurs have to ride out the tidal wave and stop it from wiping out a beach front city!
