Zane talking to his lizard, maybe asking where it hurts.
Aunt Heather sent up a box of Dana’s old toys for Zane to pick over. He may have liked a few of the others but, unfortunately, he seems to like the little piggy the most. This is the little piggy that keeps running after Zane gets bored and ends up with its snout jammed into a corner, grunting and pawing pink hooves ineffectively to nowhere, while Dad slowly goes bonkers from the sound.
From the movie below it appears that Zane has heard of piggy back rides. Obviously he hasn’t discovered they seldom, if ever, involve a pig.
