There was a point to it at least. We were learning about sleep and dreaming so he took the scene from when Lumpy arrived to his trailer to when Flippy woke up from the nightmare to show how sounds and other experiences around you while you sleep can get automatically incorporated into your dreams. So Flippy sub-consciously heard Handy's helicopter on Lumpy's tv so the next thing you know, Fliqpy shows up in the dream flying a helicopter.

Now I feel stupid that I hadn't realized that...
