Grizzy & the Lemmings (2016)

S3E33 Thermal Shock!

Title: Thermal Shock! Plot: Grizzy relaxes on the couch next to the fireplace when the Lemmings crash in, zooming around the living room on a DIY vehicle made from a vacuum. Annoyed, the bear hurls their contraption into the erupting chimney, unleashing a blast of icy air into the cabin. Desperate for warmth, Grizzy opts to relocate to the greenhouse at the nearby research facility, which is kept cozy by a drone. Unbeknownst to him, he inadvertently brings along his uninvited guests—the Lemmings!
