Scooby's Night with a Frozen Fright is the third episode of the second season of Scooby-Doo, Where Are You!, and the twentieth episode overall in the series.


Sea-fishing Shaggy catches, of all things, a caveman frozen in a block of ice, which was lost at sea after sliding off of a ship. The kids take the frozen neanderthal to Oceanland, the local aquarium. When they come back to the aquarium later that night to retrieve Shaggy's fishing pole, they find that the ice has melted and the caveman is now apparently alive and roaming the grounds.


While fishing at the beach, Shaggy snags and pulls ashore a giant block of ice containing a frozen caveman. Velma recognizes it as a two million-year-old caveman discovered in the Arctic and washed over the side of research vessel during a storm. The kids take it to Oceanland and leave it with two scientists, Professors Wayne and Ingstrom. After they leave, someone turns a space heater onto the caveman; Ingstrom leaves for the dockside while Wayne remains behind to work on some research notes.

At the Malt Shop, Shaggy remembers that he left his fishing tackle at Oceanland, and the gang returns to pick it up. They find the doors ripped off its hinges, Wayne's torn parka, and the caveman thawed out and missing. The phone is broken, so the kids decide to investigate. They follow giant caveman tracks to the dock, where they see Ingstrom working a strange device and seemingly talking to a porpoise. He takes fright and flees into a shack when he hears Scooby creeping up on him. When Freddy opens the doors to the shack, they discover the angry caveman, who chases them all about Oceanland.

After they narrowly escape, Velma finds a map showing the currents off Oceanland and an object anchored offshore. She, Shaggy, and Scooby take a boat out, where they find a fishing boat. They are locked inside it with an ice machine that is churning out giant ice blocks full blast. They escape just before being crushed by the ice, only to find that their boat has been scuttled, so they paddle back to shore on an ice block.

Freddy resolves to catch the caveman and has Shaggy and Scooby (dressed as fish) lure the caveman to a spot where he and the girls can drop a net on him. But Daphne falls, pulling everyone else down into the net. The caveman chases them again but is caught when he falls into the tank holding the giant clam. They pull him out and unmask him as Professor Wayne. Wayne had heard about the loss of the Arctic caveman and had constructed his own frozen caveman at the fishing boat, with the intent of letting it drift down to Oceanland. After its recovery, he melted it and disguised himself as the caveman with the idea of getting rid of Ingstrom and stealing his revolutionary new marine life communicator.

Full credits

The following credits are how they are seen on-screen (or as close as possible).


  • This is one of the few Scooby-Doo, Where Are You! episodes which begin in broad daylight; the most obvious other example being Decoy for a Dognapper.
  • Professor Wayne looks uncannily similar to Dr. Jekyll (also a culprit) from two episodes ago; they're also voiced by John Stephenson.
  • This episode features two instances where Shaggy physically picks Scooby up and drags him by the collar whilst scared - as opposed to bribing him with a Scooby Snack. The only Scooby Snack used in the episode is actually to prompt an idea, rather than encourage bravery.
  • This marks the first time a villain actually calls the gang, "meddling kids", though previous villains used similar terms such as "blasted kids".
  • This episode was included in Cartoon Network's Scooby-Doo! Back to School Marathon (August 10-11, 2013).


  • Disguises: Scooby and Shaggy as a swordfish and dolphin, respectively.
  • Scooby Snacks bribe: 1.

Animation mistakes and/or technical glitches

  • While Shaggy is fishing, when he says "Scooby," his mouth doesn't move.
  • When Scooby held up a fur parka, it was Prof. Ingstrom's. When the scene moves closer to the parka, it was Prof. Wayne's like it should be.
  • When Shaggy and Scooby draw the others' attention towards the absence of the Caveman, the heater next to the melted block of ice is absent. When they investigate it further, it reappears.
  • When Professor Wayne is arrested, he wasn't wearing his lab-coat and his hands are behind his back. But when the scene switches, he is wearing his lab-coat again and his hands are in front.
  • When Velma says "And that's what gave Professor Wayne the idea for his scheme," it's her voice coming from Daphne's mouth.
  • Professor Wayne's shirt is short-sleeved when he gets out of the costume and when he bujmps into the gang, but as soon as he lands, it's a regular long-sleeved one.
  • When Shaggy calls the sheriff, his mouth disappears.

Inconsistencies/continuity errors and/or goofs/oddities

  • One would think anthropologists would be better-prepared to study such a find than marine biologists. Unless Oceanland also functions as an anthropology center.
  • Oceanland appears to be some sort of Aquarium, obviously open to the public as the Gang are allowed in, yet there are no other visitors.
  • Shaggy leaving his fishing reel at Oceanland is an unconvincing, flimsy excuse to get the gang to return to find the broken "arctic" chamber, since he would have no reason to bring it there to begin with and would've surely packed it into the Mystery Machine before first going there.
  • Professor Wayne is shown turning on the heater, and then the scene pans to show him at his desk, as if he had been sitting there without turning on the heater. If he really did turn it on, he would have to move like lighting to turn it on and reach his desk and look as if he had done nothing.
  • There isn't really any need for stealth when the gang see Ingstrom on the pier. They already discern that he is talking to a fish, and it would be perfectly reasonable to ask him about it rather than being nosy. After all, they have a valid reason for being there, and Ingstrom seemed perfectly willing to talk about it at the end of the episode.
  • Wayne (as the Caveman) somehow moved between the fishing boat and Oceanland extremely quickly and without a visible mode of transportation.
  • The beginning of the episode shows the ropes breaking and the caveman sliding, hitting the ramp and falling in the water, whereas in the flashback, it shows Wayne throwing the ice cube, himself, in the water. It is likely that the beginning showed the real two-million year old caveman getting lost.
  • In the final shot of the malt shop, there are no cars parked outside, not even the Mystery Machine.
  • Velma calls the dolphin a fish even though they're actually mammals.
