I saw it on TV around 2000, it was in English and color. I remember a costume party of some sorts, it may have been outdoors. They concocted some (radioactive?) bright green slime and force fed it to a blonde kid (I think of Jonathan Lipnicki) that was locked in a cage under the table. The kids belly starts to swell and the adults force a hook or anchor through his belly button, all while cackling, and green goop pours out of the wound.
