Captain Barnacles' narwhal friends (from Season 1) are trapped under the Arctic ice. After failing to rescue them with the GUP-C's icebreaker and the GUP-D's drill, they enlist the help of some bowhead whales whose massive heads can break through thick ice.
Tropes:
- The Bus Came Back: Boris the Narwhal, who we last saw in Season 1, returns in this episode in need of some help.
- Growling Gut: A rumbling noise thought to be a sea creature turns out to just be Shellington's stomach rumbling.Shellington: I ate some of Tunip's kelp cakes for lunch, with a wee bit too much hot sauce.
- Toilet Humour: There's a gag about herrings communicating by blowing bubbles out of their behinds.
