Adventurers plops, ripe for the grabbing

You have acquired an enchanted VCR from the thrift store. Any time you play a tape in it, you summon an item or character from that tape into reality, & you don't know how to unsummon it. Some hilarity ensues.

But then you put in a tape that has been taped over too many times so that you get images ghosting over each other with a lot of static mixed in, & you end up summoning a combination of your younger self in little league attire, Dirty Harry, & a frightening stop motion crab monster.

How do you stop this thing?
