Watermelon Tourmaline,[1] also known as the Giant Pufferfish in her corrupted state, is a formerly-corrupted Gem that first appeared in "Beach Party". She was later healed (along with the other Corrupted Gems) in "Change Your Mind". After "Change Your Mind", Watermelon Tourmaline became a Little Homeworld resident.



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 gemstone is unknown because it can not be seen, it is likely that her gem is located inside her like the Gem Cave Creature.


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 white lines separate the green and 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.

Green-tipped pink spikes (possibly "scars" from her corruption) cover her shoulders where she is wearing a reddish-pink jacket wrapped around her shoulders. She also wears dark green pants, covering her feet. Her torso is large, spherical and balloon-like in appearance. She has four short arms oriented radially midway down her torso, one pair towards the front and another towards the back.

Her eyes are wide and circular with rectangular pupils, and her eyelids are not visible. She appears to possess heterochromia, with her right eye being shamrock green and her left eye being reddish pink. 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 gemstone(s) cannot be seen, and may be located on her back, under her cape.


Around 4,500 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 Watermelon Tourmaline at the beach. After Garnet is flung from the battle site by the Gem monster, Amethyst smacks the Watermelon Tourmaline far away into the ocean, allowing the Crystal Gems to regroup. The Gem monster 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, The Great Diamond Authority healed the Corrupted Gems, including Watermelon Tourmaline, in Rose's Fountain, emerging from the depths of the Fountain just a few seconds after Nephrite herself was uncorrupted surrounded by most of her now uncorrupted Crewmen. She would then be with Steven, Nephrite, and the now uncorrupted Biggs Jasper and Ocean Jasper having a conversation together when Jasper finally emerged from the depths of the Fountain, still thinking that Steven was actually Rose Quartz and summoned her Crash Helmet to attack him, only to get verbally stopped by Yellow Diamond who managed to get Jasper to calm down considerably. Amethyst would then swim past Watermelon Tourmaline to go and warmly greet her now uncorrupted "sis".

Steven Universe: The Movie

Watermelon Tourmaline appears as a resident of Little Homeworld.

"Little Homeschool"

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



  • Tetraodontid Physiology: She takes on the form, traits, and some abilities of pufferfish, 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 when she is inflated.
  • 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 is inflated with air, she can 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 which looks vastly different (and appears to be a singular Gem) appears in "Change Your Mind", it was confirmed by Rebecca Sugar in the DVD Documentary for Steven Universe: The Movie that this Tourmaline was originally meant to be this Watermelon Tourmaline's uncorrupted design, but was scrapped in favor of the current one. It is unlikely that this Watermelon Tourmaline will reappear as a result.
  • Whether or not the finalized version of her is a Fusion Gem or some kind of off-color Tourmaline, similar to that of the Rutile Twins is currently unknown.
    • Like Garnet, she appears to have heterochromia, which may be evidence of her being a fusion. However, Hessonite, a single gem, also has heterochromia. Notably, Watermelon Tourmaline did not have heterochromia in her corrupted form, nor did she have it in her initial uncorrupted design.
    • Watermelon Tourmaline has four arms; additional sets of limbs are often an indication of a fusion, as there are no known singular gems with a number of limbs that exceeds four (two arms and two legs, respectively). If her being a single gem still holds true, it could potentially be indicative of natural clustering (the phenomena exhibited by the Rutile Twins), or some kind of defect that has not yet been shown.
    • In "Change Your Mind", she is shown to have only a single gemstone just before regenerating. It is possible that this has been retconned along with her uncorrupted design.


Image Description
Watermelon Tourmaline's gemstone location is currently unknown. Her gem is shaped and colored to resemble an actual slice of watermelon. It is a hexahedron, specifically a square frustum. It is possible that this gemstone has been changed or reworked, as it only appeared in "Change Your Mind".
