Fefetasprite

Fefetasprite was Roxy Lalonde's sprite after being prototyped with Feferi Peixes and Nepeta Leijon's corpses HS 7423 (by) Gamzee Makara. Her appearance consisted of one of Nepeta's cat ear-shaped horns, and one of Feferi's slightly curved horns, similar to the Pisces symbol, her hair was of medium length (an intermediate between Feferi and Nepeta's), was extremely messy like and maybe even more so than Nepeta's, and it all curled up and had a fringe like Nepeta. Her mouth had two pointed teeth like Nepeta, and she wore goggles like Feferi. She also had one of Feferi's fins and wore Nepeta's jacket and Feferi's necklace. Fefetasprite's symbol was composed of the top half of the Pisces symbol and the bottom half of the Leo symbol.

Fefetasprite was the first B2 sprite seen to not be in immediate distress (the other being ARquiusprite), even going as far to smile and participate in the preparations for Jane's birthday party. Considering the bubbly personalities of the two characters involved, it is likely that the sprite was very happy. According to Roxy, she apparently was quite the talker and a shipping expert. Unfortunately, although the two sides of Fefetasprite were quite compatible, she soon found herself in distress as Erisolsprite and ARquiusprite competed for her attention; Feferi is dear to both Eridan and Sollux, while the Equius part of ARquiusprite desperately wanted to apologize to his former moirail for failing to protect her from Gamzee's wrath.

Unable to cope with her emotional duress brought on by the bickering between Erisolsprite and ARquiusprite, Fefetasprite eventually (dear, sweet, precious) fefetasploded. This can be likened to how Tavrisprite tavrispl♉ded earlier in Act 6 as a result of Vriska and Tavros's conflicting personalities.

Trivia

 * Curiously, this sprite could be connected with Jaspersprite, not only in the fact that both are the guides to a different Lalonde, but also that they are prototyped with a princess and a cat (or, in Nepeta's case, a cat-like being), and both have some connection to the horrorterrors. Nepeta even liked talking to Jaspers because of him resembling her Lusus, and the sprite is seen eyeing God Cat as well.
 * Given Feferi's fish theme and Nepeta's cat theme, it's possible that this combination was intentionally chosen to evoke the mental image of a catfish.
 * While she was supposedly quite talkative most of the time (according to Roxy), in all her appearances, Fefetasprite said nothing, only communicating with emotes. This could be a reference to the phrase "Cat got your tongue?" along with a reference to Feferi's Lusus being able to release the Vast Glub if she doesn't keep her voice down. There is also a possibility that, due to Nepeta's probable severe trauma in being clubbed to death by Gamzee, that she was so brain-damaged that she was unable to speak.
 * Because she was apparently only talkative around Roxy, it's possible that being around her "stole the void" normally present in her speech.
 * Due to Act 6 Act 5 Act 2 ceasing to exist, her Fefetasplosion may no longer apply.
