This iteration of the evergreen Alvin franchise is the series that has been running on Nickelodeon for a few years. I served as a board artist on a couple of episodes.
This is the music montage sequence from the episode “The Flying Chipmunk” in which Alvin desires to try the parachute suit wind machine attraction at a local amusement park. He is too light and too short for the attraction, so he sneaks in to ride it after hours. This montage sequence shows Alvin’s attempts to adjust his height and weight, and then imagines how great the overall experience will be.
