Spinners are a little bit aggressive than Hoppers in Epic Mickey. To defeat a Spinner, you must spray Paint Thinner on him. Since all machines are emotionless, Paint cannot redeem a Spinner; just slow down its buzz-saws. Once you've erased its shell, you must attack it with your Spin Move. That will deal more damage.
These and Bashers and Tankers are dangerous during the battle with the Mad Doctor, since you must have enough TV Sketches or Watch Sketches to distract them and erase the red toon eye on the Beetleworx Generator. It is advised to avoid them at all costs.
In Epic Mickey 2: The Power of Two
In Epic Mickey 2: The Power of Two, The Mad Doctor redesigned and reprogrammed some of his Spinners, claiming he's a reformed toon, and to help Wasteland with all of his supposedly reprogrammed Beetleworx. One of the Spinners is a smiling lady bug based on one of the forgotten floats from the Disney Parks, it also appears in the Floatyard. The scrapped Tea Cup variant that was going to be used in the first game appears in the Train Tunnels. An unused variant appears in the credits, based on Toad of The Wind in the Willows.
