Halloween Nick Rewind
CatDog: CatDogula
S1 E4:
It's Halloween and Cat, dressed as Duke Kahanamoku of Hawaii and Dog, dressed as Count Dogula, go out Trick-or-Treating. Dog is bitten by Nosferacho, a Peruvian vampire tick, and turns into a vampire. Then the tick bites Lola, Rancid, the Greasers, Mervis, Dunglap, and Randolph and turn them into vampires, too. Armed with his garlic lei, Cat heroically fights off Dog, the vampire mob, and the Peruvian vampire ticks, then soaks them all in garlic juice to make them normal again.
