Beetlejuice (1989)

S4E54 The Chromazone

Beetlejuice finds himself sucked into The Chromazone, a parody reminiscent of The Twilight Zone. In this bizarre realm, he must assist Tod Sperling in vanquishing Ima Loony, one of his own creations, who has taken to scripting her own narratives. However, as chaos ensues, Beetlejuice literally loses his mind in the struggle. If Lydia can't make it into The Chromazone soon, Beetlejuice risks becoming empty-headed and utterly dull for all eternity.
