The Ice Melt Cometh!
S1 E22:
Doom sends out his "Team Toxic" (Pyro, Paste Pot Pete & Zzzax) to melt the polar icecaps. While Flatman and Reptil are lecturing on the dangers of global warming, the icecap melts and begins to flood the whole world! The earth's only hope is a cranky Iceman if Iron Man can convince him, that is.
