This week on The Nerd Nebula, the fearless (and questionably competent) trio of Jay, Brother Barkington, and Kowasu embark on a high-seas adventure in the tropical waters of Star Tropics. Their mission? Capture a great white shark pup for a shady vendor. Simple, right?

Well, as fate (and poor navigation skills) would have it, our heroes end up sailing a little too far north. Instead of a paradise filled with sunshine and sharks, they find themselves in the freezing polar oceans—where their biggest problem isn’t the temperature, but the gang of very territorial ocean unicorns (also known as narwhals) now circling their boat.

Do narwhals have a strict "no trespassing" policy? Yes. Are they willing to joust intruders with their majestic tusks? Also yes. Can Brother Barkington charm them with interpretive dance? Probably not, but he's not going to try anyway.
