Brad and Tucker (and Grumbo) are having a merry time having another sleepover at Mike's house until something strange happens...the portal next to Jimmy's house lights up, becoming stronger and materializing objects out of its door. Then, Mike begins to feel strange and starts to fade away. But what is going on? Can Brad, Tucker, and Grumbo save the day? Will Mike be okay? All of these questions may be answered, or not. You'll just have to tune in!
