Yellow Planet

Plot

A viewer chooses to watch the nature film Yellow Planet. During the Arctic summer, Homer, a beluga whale, and Marge, a narwhal, meet and fall in love. When the season ends, they migrate separately. Moe urges Homer to follow Marge.

Homer joins Marge’s pod, claiming his own pod was killed by orcas, but her father Rainier Wolfcastle remains doubtful. In the Galápagos Islands, Bart the iguana learns to evade snakes. He realizes the snakes cannot detect movement, so he shoves his fellow iguanas forward as sacrifices to survive. In Africa, Flanders the mandrill and his sons debate evolution.

Homer and Marge dive deep to find food, tearing a parody of Ursula from The Little Mermaid. After feeding and sharing food with the pod, they plan to marry—until they encounter Homer’s pod. Marge’s pod abandons him when his lie is exposed. In the Amazon rainforest, Lisa the woodpecker finch teaches others to use twigs to lure ants from trees.

They eat all the ants, killing the trees, then scavenge from an Amazon warehouse dumpster. Kirk the praying mantis catches Luann eating another male after mating; they argue, and she decapitates him. Jacqueline tries to comfort Marge, revealing she once loved a gray whale but ended it to obey her parents. Marge, determined not to repeat this, searches for Homer, now a performer at a water theme park.

When Marge forgives him, Homer tries to escape, accidentally killing his human trainer. He is released, mates with Marge, and they have Maggie, a narwhal-beluga hybrid. Finally, Morgan Freeman appears to the narrator, warning him not to make a documentary about penguins, since Freeman already made March of the Penguins.
