She's the ghost that bugs people until they die! Until then she'll be their closest acquaintance, perhaps best pals. The reason for this is because she has no desire to achieve anything.
She can possess stuff like bookshelf with books in it. Her holding a hammer is something like that.
She liked computers and music. She used to have good grades and performed terrific in school band. She had interest in C and made many weird things that survived to this day. She died when she was 14 due to heavy snow that destroyed her house. Unfortunately that made her 14 forever. She's either cringe or based.
Osialfecanapomagne-the demon of Dream Realm thought she was really based and could help her reach out to reality. But unlike her expectation Simmon's 'hatred toward the society' was actually just 'hatred toward one specific person that makes her angry'.
Osi didn't really figure this out even after Simmon told her to f off, but in the end she accidentally spills entrophy onto her and Simmon becomes a ghost instead of dying and returning to the cycle. Not that she minds though because now she feels really empty-headed all the time, just like she imagined herself doing her whole life.
This is old design of simmon when she had fingers and eyes
What would ghosts even wear....
I'm really proud of that lil drawing depicting simmon as snake game snake.
