Humphrey Spoolman used to work to there in Drive-In Me Crazy. He wanted to swap Burt a popcorn machine at The House Of Swap. He planned on closing it down but he then make a swap the Drive-In with Dad for the sunglasses and the float and he did.
He planned to re-open the place tonight with help from Coop, Dennis and Millie by tiding up outside and inside. However Kat was thrilled about what Burt said monsters and spaceships jumping out of the big screen so he builds a 3D device and puts it in the lens of the Projector to brings them all to life with a flick of a switch.
