Lemme see....... Maybe that he loses his Robot???? I mean dr.zomboss (Himself) Is pretty much a coward for surrendering. Even imps attack your plants while they are small and almost chanceless... And the main leader surrenders. So yep dr.zomboss is a coward.

But the robot???? I have no idea what his weakness should be :/
