The pumpkin is huge and can easily impale people with its spikey tentacle things. It can grow more tentacles and the tentacles are very strong and smell like rubber mixed with pumpkin flavor and human insides. The origin is that the pumpkin was that it was in a nuclear power plant during a meltdown and was near rubber. The area exploded and left waste everywhere, and the rubber and pumpkin mixed and started growing large. It killed a few people while growing, leaving the smell of gore stuck inside.
It actually started living as an fnf concept, then now it is here.
