The Microwave

The Microwave was the main antagonist in "Greatest freak out ever 5". It was smashed by Stephen after not working multiple times in the backyard by getting thrown to the ground and smashed by a rock. Its name was "A Really Really Crappy Microwave That Won't Cook Anything" by Jack and "A Freaking Piece of Crap That Doesn't Cook" by Stephen.

Replacement
Although the replacement for the microwave isn't seen, in 16 and 17, a few cookbooks and other object can be seen in the microwave's former spot before it got destroyed.
