"Super Watermelon Island" is the first episode of the third season of American animated television series Steven Universe, which premiered on May 12, 2016 on Cartoon Network.
Steven wakes up at his family's barn in his own body and tells Garnet (Estelle), Amethyst (Michaela Dietz), and Pearl (Deedee Magno Hall) that Malachite is active.
They tell Steven to stay put with Peridot (Shelby Rabara) while they go to the island to fight Malachite.
On Mask Island, the Crystal Gems fuse into Alexandrite (Rita Rani Ahuja), and she and Malachite engage in battle.
Before she can finish her off, the Watermelon Stevens begin their assault, managing to down and distract Malachite for long enough for Alexandrite to free herself.
She soon gains the upper hand and defeats Malachite, who de-fuses into her component Gems, Lapis Lazuli and Jasper, both unconscious.
James Whitbrook of io9 declared the entire In Too Deep event as the "show at its best" and said the episode provided an effective and satisfying close on the current storyline.
