Some TMNT stuff really isn't for little kids.
The Eden Worlds are planets that were reminiscent of the wilderness of East Africa where most "intelligent" species were forbidden to live on those planets. The planets were devoted by the Elder Races.
In "Raw Power," Rocksteady and Bebop obtain some clothes and some guns where they begin their plan to emigrate the local zoo animals to their Eden World. Rocksteady and Bebop succeeded in their mission and dropped off Krang and Bellybomb on Morbus before returning to their Eden World with the zoo animals.
In "Paper or Plastic?," the Teenage Mutant Ninja Turtles encounter a naked Rocksteady and Bebop in the grocery store where they'd come from Eden World to get some snacks, attempting a barter (a word that Leo had to teach them) instead of steal, but everybody had run off. As the mutants are talking, Raphael and Ninjara suddenly attack Bebop and Rocksteady. Bebop and Rocksteady take off with their snacks, with Leonardo using Splinter's cheese money to pay for their food.
