I'm in a huge house trying to deal with a shelf full of strange crab-like creatures. They crawl about, dripping a sap-like liquid all over the place. One creatures (which looks like a king crab) scurries off the shelf and onto the floor on its back. I run after it, grabbing an oven mitt from under the TV. As I chase it, the doorbell rings. I try to visually track the crab while I run over to the buzzer. It has three buttons, two of which seem to be for calling the house together for a meeting. I press the third button, then go and grab the crab.
