Calling Dr. Zak Dragon Tales : Season 1 Episode 8

Max and Emmy go to Dragon Land and bring musical instruments with them. Today's the day for Zak and Wheezie to be in the two-headed dragon contest. They're singing a dragon version of "Knick-Knack-Patty-Whack." Just then, a spiny-pine appears, attracted by some fruit that spilled from Wheezie's decorative hat and Zak accidentally steps on it. Wheezie recommends going to see the doctor, but Zak's scared. But without getting out, they can't do the contest.
