Scooby-Doo! Moon Monster Madness
While Zip Elvin and Colt Steelcase worked on repairs for Sly Star One, Fred Jones played around with stuff, including the coolant gel which he accidently sprayed on Daphne Blake. Fred was about to help her, when he was distracted by a oxygen tank imbued with nitrogen, freezing himself. The astronauts decided to leave Fred the way he was for about half an hour, but unfortunately left Daphne struggling in the same spot, too.
