123Movies. In 'Trapped', we see the cartoonist's hands as still photograph cut-outs, manipulated in front of the camera to look like live-action movie footage. The hands sketch a small black dot and ink it in. Then the dot proceeds to bounce across the cartoonist's easel, until the hands finally catch it and unfold it into Ko-Ko the Clown. There's a mouse in Max's studio, and Ko-Ko wants to catch him.
