All the people are scared of pollution in the sea, so Stitch has to defeat Ploot in order to save it.

Kijimunaa's sister, Kijimaggie, who looks like him and is pink, visits Izayoi. She worships her brother, believing him to be brave and strong, not knowing how cowardly he is. Her belief is shattered when Kijimunaa is unable to destroy a meteor hurtling towards Izayoi and Stitch does so instead, saving the island. Kijimunaa then finds a strange but hurt living plant on the ground and plants it; noticing his kindness, Kijimaggie's faith in him is restored. What they don't know was that the plant is actually an offspring of Jumba's Experiment 509, Sprout, who was on the meteor that Stitch destroyed, and soon the "Sproutling" grows big and aggressive. Other Sproutlings grow all over the island, strangling everyone with their vines. Stitch tries to stop the Sproutlings by uprooting the main one, but even he is unable to. Kijimunaa notices a tear at the base of the main Sproutling's stem and cries over it, causing one of his magic tears to fall into the tear, healing the Sproutling, returning him to his original size, saving everyone, and causing Kijimaggie to see him as a hero again.
