I'm not sure if this movie is the argon quest but it's a kids movie with muppets. The snake is the bad guy and they are on some kind of quest or adventure. The end of an episode or movie or some part they are on a boat and the 'And we're hot hot hot' song is playing. Then the snack drops down from the trees above and everyone freaks out. Can you help me find out what movie or show this is?
