The Flue Shot takes the form of two objects: a stereotypical red brick chimney with a gray mouth and while snow on its foot, and a yellow iron ball with gray spikes and a red bow wrapped around it that is expelled from the aforementioned chimney.
When used, copies of the Flue Shot's chimney will be dropped some distance ahead of the user's current location on each of the lanes available on the road. Shortly after being deployed, half of the chimneys will then each expel one of the Flue Shot's iron balls and keep them suspended above them; which one of chimneys that will expel an iron ball is chosen at random. Should a playable character (including the user) touch the Flue Shot's iron ball or chimney, they will take damage and be slowed down temporarily. The Flue Shot can be also upgraded for each individual user by leveling them to levels 4, 10 and 16, increasing the damage the Flue Shot inflicts.
To avoid a Flue Shot, the player's only option is to jump over a chimney that does not have an iron ball above it.
