Isn’t that the one where Joey ends up sent into a kind of purgatory and chased by the manifestation of death?

Yep.

That was probably originally Hell, wasn’t it?

Originally? They just straight up killed you. But for some bizarre reason, 4kids in the US went "Kids can't deal with death! Let's instead make a realm where they go! Yeah! A realm they don't want to be but that way they don't die! Forever!"

4Kids straight up invented a version of hell because they were too terrified of just saying "People gon die."
