Invader ZIM - Return of Keef (with anime) (old)

Keef, who originally appeared in "Bestest Friend", comes back to be Zim's friend again, but then becomes friends with Dib when he realizes that Dib, although happy with his paranormal-dedicated life, is extremely depressed by nature. He notices this after Zim pours a popping solution on Dib that will only activate when he's happy, which he never really is. Keef tries to get everyone happy, not knowing about the popping solution and only noting Dib's depression. When he starts to become even more annoying than before, Dib and Zim have to team up in order to get rid of him. During this, Zim actually admits he's an alien in front of Keef, even though he's scared of a human ever realizing it. Keef gets so happy by how Zim and Dib appear to be friends, he pops, having become covered in the popping solution, and Zim says he will be out for a few weeks. images from: invaderbuzzy, Hoshikane clips from: TheCanJay    / thecanjay
