Fidget Spinner

The fidget spinner tower is a tower you get by beating the toy event. It summons a single projectile that sticks on its target and deals constant damage. It also turns into a sawblade/gorilla launcher in later levels. A Discord user named ZombiePhysician, Purple Warlord #3700 suggested it, and the character wielding the spinner is ANYONPOGI, someone who also contributed to the toy event.

The way this tower works is it straps on a projectile to an enemy and the projectile will keep doing damage until it expires or the enemy dies. However, this is a confuseing and misleading explanation due to how timing works; ultimately the tower works more like a tower that will lock onto an enemy and will only deal damage to it for a couple seconds and retarget after that interval, but does not retarget before that no matter what (target dying or going out of its range doesnt matter).
