S1·E13 The Giant of Nod

Zak and Wheezie practice for tonight's concert hosted by Quetzal at Singing Springs, but they war over various songs they wanted to play and disturb the nap of a twelve-inch creature known eponymously as "The Giant of Nod". He desperately throws them in a tree trunk, so it's up to them to save the gang so they can make it to the concert.
