Megablast is excited to play the school dance. Meanwhile, Stewey is listening to his favourite song on a tablet device, but it abruptly stops when the battery dies! This doesn't go over well with Stewey who becomes Gooey and he slimes anything that plays music because he doesn't want to hear any music if it can't be his favorite song. Megablast transforms into Rocket, Thunder and Metallix to save the day and get back to the school in time for the dance start.
