Beetlejuice S02 E01 Dragster of Doom

Beetlejuice and Lydia decide that it's time for them to have a car of their own, so they rebuild a salvaged one they find in a Neitherworld wrecking yard. But BJ delivers Lydia an abnormal carburetor for installation and although the car they create looks normal at first, it soon becomes evident that he's abnormal.
