Pickle can't whistle (cap.3)

Miss Meadows has a music lesson and teaches the class to whistle, everyone joining in except Pickle, who just can't do it. The Megaminimals go out of their way to help the penguin learn but he just can't seem to manage it and is disappointed because he wanted to join in with the big song planned for the end of the lesson. Eric tries to give him some extra coaching and finds that Pickle can't whistle, but he's great at humming! The big song starts and Pickle is a star performer with his great humming!
