S2 E103: There's a heat wave in B-city and the Bubigirls use their free time to make a surprise party to Batny. He is celebrating his birthday at Bubilab with his friends the Bubiloons when he hits his head on a ball and then he starts to get dizzy. The Bubiloons should take care of him while they try to guess what his favourite sweet is to tell Bubigirls to prepare it to him as a surprise.
