Spinners are a variety of Beetleworx. They are spider-like robots with shells covering them and they are equipped with buzzsaws. They can be found in Tomorrow City and Lonesome Manor. In Tomorrow City, they look like the instrument from treasure planet, while in Lonesome Manor their shells are loosely based off the spiders that appeared in the 1933 short The Mad Doctor. Use Thinner to erase their shells and they will fall on their back, then use the Spin Move to do some damage to them. Using Paint will slow down their buzzsaws.
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 Disney Parks, it also appears in the Floatyard. The scarpped 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
