"That Which Cannot Be Unseen" is an episode of Monsters vs. Aliens. It premiered on February 1, 2014.


Everyone in Area Fifty-Something agrees Coverton is unpleasant to be around, much less like. Today, there's something in his room that causes Team Monster and Sqweep to use her memory eraser. Which seems fine, unless a concerned B.O.B. wants to help his alien friend and everyone is constantly having memory loss.
