Eddie gets psychic powers, and brags about it which makes him popular and making Raven mad at him. Meanwhile, Cory gets hooked into this Crime Disco movie, "Undercover Disco Divas".
When the Baxters were watching Undercover Disco Divas, the woman with the brown wig was called Coffe and the one with the blonde wig was called Cream. When Raven and Chelsea dressed up as them, it was the oposite.
Undercover Disco Divas was meant to be filmed in the seventies. Back then, it was against the law to show your belly button on television. Coffee and Cream show wheir bellybuttons.
It seems odd that Corey wasn't punished for misbehaving in school and forbidden to attend 70s Night.
