Symbols' is a reference to Caroline and Nurse Doom from Sparklecare. However, it’s just a reference to Caroline from Sparklecare and corru.observer. The cape is not a reference to Nurse Doom from Sparklecare, thats unintentional.
Symbols is a female that wears a dark blue witch hat with a pink neon ring on it and has some dark blue cat ears on it. Her cape is also dark blue with some of the symbols (hence her name) she has. it’s like a OwO but if it was from a horror analog.
