When Jelly wonders what a unicorn is, Narwhal explains that they're pretty much narwhals of the land (!) -- and then gets carried away with a grand plan to see one. With the help of Star, Narwhal's wish comes true in the wildest, weirdest way: Narwhal gets some land legs and takes their first step ashore. After some wibble-wobbling and a bit of practice, Narwhal is soon galloping along in search of unicorns, though Jelly is a little land sick. Before they know it, Star has the duo blasting off to a magical planet where everyone is a unicorn! But Jelly's out-of-this-world adventure makes him feel out of his comfort zone, and he wishes he were at home . . . can Narwhal cheer Jelly up and also party down with their new unicorn pals?
