Wrench (スパナ, Supana?, lit. "Spanner") is an item in Tails Adventure. The Wrench can be found in Battle Fortress 2 in a section only accessible by using the Remote Robot. When the Wrench is used, the player can reverse the moving direction of Conveyor Belts in Battle Fortress 2. Interestingly...

This is also why its easy to fuck with them. Look at the Chris Chan saga or like, a lot of Youtubers, like I dunno Technology Connections. You see people do lots of mean spirited shit but as linguistic gymnastics. The autist won't get it and for instance in Chris Chan's case they can be convinced to do weird shit that way. However if you question them directly they will understand that. And often get pissed off because for an autist they simply cannot decipher tone on the internet so if you ask them something simple you have a 50/50 chance of them taking it personally. Any of us who have gotten a DM from Nolan know this.
