The Jewel Damsel is noticeably larger than all of the other Damsels. It has a main body color of dark blue, the only other color visible being a lighter, neon blue. This is visible in square spots around its body, clustered more closely together towards the tail fin. Its pectoral and pelvic fins are also colored neon blue, and its anal and dorsal fins have a thin stripe of this color along their edges. Its tail fin is mostly neon blue, but some of its is the darker blue color.
To unlock the Jewel Damsel, the player must tap the upper left corner of the screen 1000 times. The acceptable area for this task is relatively small, but the player should be able to fit three fingers in it for tapping.
The Jewel Damsel can be used to reveal the Cross Damsel.
The Jewel Damsel is relatively similar to the juvenile version of its real-life counterpart of the same name. In the wild, they are found in the western Atlantic ocean, and mainly consume algae and zooplankton. They are popular in the aquarium trade, but are extremely aggressive and territorial, meaning only one should be kept in a tank at a time.
