The Day the Earth Disappeared

Dregg's plan to suck the entire Earh into Dimension X is the same plot as Shredder and Krang's plans from the Season 3 finale, The Big Blow Out.

Errors

When Leonardo and Donatello arrive in the planetoid, the sky is yellow or green. But when they fight the groun vines, the sky is dark blue.

When Leonardo and Donatello fight the ground vines, Leonardo had Raphael's bandannas and the "R". Earlier, he had Raphael's colors when he reached out his arm to Donatello.
