Thermal Shock! - S3.E33

Grizzy settles down on the couch by the fire, when the Lemmings tumble into the middle of the living room riding a makeshift mount with the vacuum cleaner. Irritated, the bear throws their mechanical steed into the exploding chimney. Freezing cold enters the cabin. Seeking warmth, Grizzy decides to move into the greenhouse at the nearby science station, which is air-conditioned by a drone. But the bear doesn't know he's bringing in his luggage ... the Lemmings!
