Hey, I remember an episode of "Muppet Babies" where in the beginning of it, there was a scene that reminded me of the Scooby-Doo episode "Mine Your Own Business." A part in that Scooby episode had Scooby and Shaggy pretending to be a train in a tunnel, with Shaggy making "NNNNNNN!" noises like a train horn and Scooby using a flashlight. Well, in this Muppet Babies episode, in the beginning they fantasize exploring in dark tunnels. Gonzo goes in a tunnel alone, and then sees a light coming toward him with an "NNNNNNN" sound (and they show an actual clip of a train coming), and Gonzo runs away, and the "train" was revealed to be only Kermit and Skeeter with a flashlight. I've been trying to figure out that episode for years. Can anyone help me?
