"Rock to Sleep" is an episode of The Fresh Beat Band from the first season.
Shout gets a bugle in his favorite box of cereal. He plays with it all day, and even into the night. Shout knows it is time to go to sleep, but he can't help himself. He keeps playing his new bugle. Kiki, Marina, and Twist all want to go to sleep, but Shout's bugle playing is driving them nuts. The three of them have to work together to figure out a way to get Shout to go to sleep.
