Watermelon Tourmaline,[2] known as the Giant Pufferfish in her corrupted state, is the fusion of two Gems (presumably Tourmalines) who made her debut as a corrupted Gem in "Beach Party". She was later healed (along with the other corrupted Gems) in "Change Your Mind". Watermelon Tourmaline became a Little Homeworld resident, partaking in Little Homeschool as well.



The upper half of Watermelon Tourmaline's body is colored shamrock green while the bottom half of her body is colored light pink.

Her body is covered with spikes, with the spikes on the upper half of her body being more numerous and much longer than the spikes on the bottom half.

She has diamond-shaped turquoise pupils with slanted mint-colored eyelids and dark grayish-green colored lips. The location of her gemstones is unknown because it can not be seen.


The top half of her head and lower torso are shamrock green, while her shoulders, upper arms, and the lower half of her head are light pink. Jagged light shamrock green lines separate the shamrock green and light pink sections of her body. She is completely bald, with rounded facial features and no neck, with large puffy cheeks that appear to have a dark pink blush.

Shamrock green-tipped light pink spikes (possibly scars from her corruption) cover her shoulders. She also wears a reddish-pink shawl, with the spikes on her shoulders puncturing through it. She also wears dark green pants, covering her feet. Her torso is large, spherical and balloon-like in appearance, with four short arms oriented radially around its "equator", one pair towards the front and another towards the back.

Her eyes are wide and circular, and her eyelids are not visible. Her lips are much less defined than those of her corrupted form, and are the same color as the rest of the lower half of her face. Her gemstones are placed where her pupils would otherwise be, with the gemstone on her right eye being shamrock green and the one on her left eye being reddish pink.


Little is known about Watermelon Tourmaline’s personality. Her concept art from Steven Universe: End of an Era describes her as a "Gem version of Onion", implying that she's quiet in the sense that he is. Throughout the franchise, she appears to be cheerful.


Around 5,050 Years Ago

At the end of the Rebellion, Watermelon Tourmaline was unable to escape the corrupting light and became corrupted.

"Beach Party"

The Crystal Gems clash with the corrupted Watermelon Tourmaline at the beach. After Garnet is flung from the battle site by the corrupted Gem, Amethyst smacks Watermelon Tourmaline far away into the ocean, allowing the Crystal Gems to regroup. The corrupted Gem later returns to the beach and is eventually defeated by the joint effort of the Crystal Gems and the Pizza family.

"Change Your Mind"

Following the battle on Homeworld, Steven and the Diamonds healed the Corrupted Gems, including Watermelon Tourmaline, in Rose's Fountain, with Watermelon Tourmaline emerging from the depths of the fountain just a few seconds after Nephrite was uncorrupted. She was then with Steven, Nephrite, and the now uncorrupted Biggs Jasper, Ocean Jasper, and Angel Aura Quartz, having a conversation together with them before being interrupted by Jasper approaching them fiercely.

Steven Universe: The Movie

Watermelon Tourmaline appears as a resident of Little Homeworld.

"Little Homeschool"

Watermelon Tourmaline makes a very brief cameo; as Steven gives a recently uncorrupted Cherry Quartz a tour of Little Homeworld, Watermelon Tourmaline can be seen jovially bouncing past them.

"Together Forever"

She attends Sapphire's class on the beach.

"The Future"

Watermelon Tourmaline is seen walking down the sidewalk in the background.


Watermelon Tourmaline possesses standard Gem abilities, bubbling, shapeshifting, fusion, regeneration, agelessness, and superhuman strength/durability.


  • Tetraodontid Physiology: She takes on the form, traits, and some abilities of pufferfish when corrupted, allowing her to inhale air to increase her size to appear more threatening.
    • Spiky Defense: Like diodontidae-type pufferfish, she possesses sharp spines, which radiate outwards upon inflation.
  • Respiratory Strength: She has the power to spew an incredibly powerful gale which is strong enough to blow away Pearl's spear mid-throw and even Garnet herself.
  • Enhanced Durability: She seems to have high durability, as she was able to endure Amethyst (as a giant bat) hitting her into the ocean. However, because she was inflated with air, she could be defeated by being pushed into a sharp object with enough force to pop her.


  • Ball Bounce: Watermelon Tourmaline's more spherical form allows her to bounce on surfaces rather than walk or run.

Episode Appearances


  • Watermelon Tourmaline's name was first revealed by former crew member Ian Jones-Quartey on Tumblr.
  • Her previous uncorrupted design resembles that of two unidentified gems seen during a flashback in the episode "The Answer", albeit with spines. It is possible that the aforementioned individuals are also Tourmalines, though as a result of her redesign in Steven Universe: The Movie onward, the possibility of this is rather dubious.
  • A Watermelon Tourmaline who looks vastly different (and is a singular Gem) appears in "Change Your Mind"; it was confirmed by Rebecca Sugar in the DVD Documentary for Steven Universe: The Movie that the design seen in "Change Your Mind" was originally meant to be Watermelon Tourmaline's uncorrupted form, but the design was scrapped in favor of her current one.
    • In "Change Your Mind", she is shown to have only a single gemstone just before regenerating. This was later retconned along with her uncorrupted design, in favor of her being a fusion.
  • Her pupils were revealed to be her gemstones in Steven Universe: End of an Era.
    • This officially retcons her gemstone design from "Beach Party".
  • She and Crazy Lace Agate are currently the only known fusions to have been corrupted in the series.
    • Watermelon Tourmaline is also the first fusion to involve a corrupted Gem in general (the second being Zebra Jasper).
