This is code for turn on the treadmill and make a giant mess.
I do love the creativity of it... it started with the play food bucket. He would take out the play food (say, an apple) and put it near the top of the treadmill belt. Then, he'd turn on the treadmill and the apple would make its way down the "assembly" belt. Soon, the food bucket was empty, thanks to the help of his assistant, Marissa, who would hand him something each time an item fell off the belt.
Every toy in that playroom has been on the assembly line... big toys, little toys, you name it.
