Spinner

A Spinner, originally known as a Ball 'N' Chain  (also spelled Ball 'N Chain, Ball 'n' Chain, or Ball and Chain ), is a spiked ball on a chain first appearing in Super Mario World. Spinners are usually found in castles and similar environments and are often indestructible. Their behavior varies depending on the game, switching between spinning around in a circular motion and swinging repetitively in a pendulum motion. The chain also changes, with most games allowing Mario to safely pass through it unharmed.

Super Mario World
Ball 'N' Chains first appear in Super Mario World, in castles and fortresses. They continuously rotate from a Gray Block. 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 intended to be destroyed.

New Super Mario Bros.
Rotation-style Ball 'N' Chains reappear in New Super Mario Bros. They only appear in. The blocks are still there, and one even has a Star Coin. Aesthetically, they spin wildly on the end of the chain as well as rotating on the block; however, this does not affect their attack.

New Super Mario Bros. Wii
Rotation-style 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 (known here as Swing Spikes ) appear in purple with yellow spikes and chain. Like some earlier appearances, they are not linked to shackles. Instead of performing complete rotations, they only make pendulum movements. They can be destroyed by making contact with them as Invincible Mario, White Tanooki Mario, or Statue Mario. The first level they appear in is.

New Super Mario Bros. U / New Super Luigi U / New Super Mario Bros. U Deluxe
In New Super Mario Bros. U, New Super Luigi U and New Super Mario Bros. U Deluxe, they appear under the current name Spinner, which is a retranslation of the original Japanese name. Regular and giant versions appear, once again swinging in a pendulum-like manner. These Spinners cannot be avoided by passing through the chains, as they have been spiked like the iteration from the Yoshi's Island series. 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
Rotation-style Ball 'N' Chains appear in Super Mario World 2: Yoshi's Island. They are colored orange instead of black, and usually found in forts. Their chains are replaced by spiked bars, some of which are double-sided. Hacking shows that they can by destroyed by Superstar Mario. They, along with similar objects such as Tekkyū Dosun, are operated by certain Boo Guys.

Yoshi's Story
Ball 'N' Chains appear in Yoshi's Story, where they swing in a manner similar to pendulums for the first time. Unlike Super Mario World 2: Yoshi's Island, their chains are harmless. They are found alongside Tekkyū Dosun-like iron balls, which share the same graphics. Both appear in the stages The Tall Tower and Magma Castle.

Yoshi's Island DS
Ball 'N' Chains, known as Spinning Spikes, reappear in Yoshi's Island DS. They act they do in Super Mario World 2: Yoshi's Island, except they are operated by background Shy Guys.

Yoshi's New Island
Spinners reappear in Yoshi's New Island. Their behavior remains unchanged, except they operate automatically instead of manually.

Yoshi's Woolly World / Poochy & Yoshi's Woolly World
Spinners also appear in Yoshi's Woolly World and Poochy & Yoshi's Woolly World. This time, they look closer to their New Super Mario Bros. U redesign, but retain their fully-rotating behavior from the Yoshi's Island series.

Super Princess Peach
In Super Princess Peach, pendulum-style Ball 'N' Chains appear in Bowser's Villa, where they swing back and forth between the background and foreground. The chains resemble their appearance in Super Mario World, but the spiked balls are green, having a resemblance to Bowser's Shell.

Mario & Luigi: Partners in Time
Motionless Ball 'N' Chains make a minor reappearance in Mario & Luigi: Partners in Time, where they are seen hanging from the ceiling as decorations in Bowser's 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. Unlike in previous games, the spikes on the ball appear to be blunt, similarly to Thwomps.

Mario Party 10
Pendulum-style Spinners appear 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.

The Super Mario Bros. Movie
In The Super Mario Bros. Movie, Spinners act as the anchors for Bowser's ship.

 Spinner  Tribe: Mecha clan Disposition: Serious Game appearances: World ' An obstacle that can only be avoided ''As its name suggests, it is an iron ball that goes around and around. The only way to get past them is to avoid them. The chain part is safe to touch, so take your time at the base of the chain to get through.''
