Spinner

A Spinner, originally known as Ball 'N' Chain (also spelled Ball 'N Chain or Ball and Chain ), is a spiked ball on a chain first appearing in Super Mario World. They are usually found in castles, and are indestructible. In most games, Mario can safely pass through the chain unharmed.

Super Mario World
Ball 'N' Chains first appear in Super Mario World, in castles and fortresses. Also, using a Spin Jump will allow Mario/Luigi to harmlessly bounce off the spiked ball. The only way this obstacle can be defeated is by using a Super Star, but its sprite will change into a defeated Bony Beetle, as it was never programmed to be destroyed.

New Super Mario Bros.
Ball 'N' Chains reappear in New Super Mario Bros.. These obstacles are very rare, with their only appearance in. The blocks are still there, and one even has a Star Coin. As an added feature, they rotate wildly on the end of the chain as well as spinning on the block; however, this does not affect their attack.

New Super Mario Bros. Wii
Ball 'N' Chains reappear in New Super Mario Bros. Wii once, in and in a secret area of.

Super Mario 3D Land
In Super Mario 3D Land, Ball 'N' Chains appear in purple with yellow spikes and chain. This time, they are not linked to shackles, like in Super Mario World. Instead of spinning, they only make pendulum movements. They can be destroyed by making contact with them as Statue Mario. The first level they appear in is.

New Super Mario Bros. U
In New Super Mario Bros. U, regular and giant Spinners appear, swinging in a pendulum-like manner as they do in Super Princess Peach and Super Mario 3D Land. Unlike other iterations, however, these Spinners cannot be avoided by passing through the chains, as they have been spiked too. Mario can pass through Spinners while under the effects of a Super Star, though he cannot destroy them.

Super Mario World television series
A Ball 'N' Chain makes a brief appearance in the Super Mario World animated series episode "Send in the Clown". Mario, while traveling through Neon Castle, narrowly avoids being hit by a Ball 'N' Chain that drops from the ceiling as he traverses over some lava.

Super Mario World 2: Yoshi's Island
Ball 'N' Chains appear in Super Mario World 2: Yoshi's Island. They are colored orange instead of black, and they are usually found in fortresses, and have spikes on their chains. Another type, called Tekkyū Dosun, also appears. They have spikeless chains and are operated by certain Boo Guys. Hacking shows that Superstar Mario could eliminate one.

Yoshi's Story
Ball 'N' Chains reappear in Yoshi's Story where they either swing in a manner similar to pendulums or quickly drop down to the floor and then slowly rise again. They only appear in the levels The Tall Tower and Magma Castle.

Mario Kart 8 / Mario Kart 8 Deluxe
In Mario Kart 8 and Mario Kart 8 Deluxe, a single Spinner appears as an obstacle in Bowser's Castle. The obstacle acts virtually the same as the pendulums in Tick-Tock Clock, except that the player will spin out upon hitting it. The Spinner will move faster during the final lap of the race.

Mario Party 10
Spinners reappear in Mario Party 10 in the minigame Spiked Ball Scramble, where they hang from the ceiling and swing across the path. They can be encountered in a standard and a larger size, and take out players in one hit.
