Milo's brother has given him a whoopee cushion (which Bella thinks is a balloon at first), and he and Bella set about using it to play a practical joke on the others. Bella and Milo go on to find other jokes, but unfortunately Jake becomes the main victim. His sadness is helped by Max showing how to make a practical joke of his own. He then uses this knowledge to get his own back on the others. Friends again, they team up to play the best practical joke of all on Max.
