Spiny (Dance Dance Revolution: Mario Mix)

Spinies are obstacles that appear in Dance Dance Revolution: Mario Mix. Multiple types appear in the game.

In the Mush Mode versions of Stage 2-3: In the Whirlpool, and Stage 2-3EX: Step by Step, they sometimes appear in place of an arrow and look like metallic spheres with spikes, and have black rims, essentially appearing to be mines. When the player steps on a Spiny, they will explode (also not unlike a mine), causing the player's dance meter to decrease significantly. Spinies appear in red and green colors, with the red Spinies moving faster than the green ones.

Spinies also appear in the minigames Banana Storm and Coin Collection, where they resemble orange Spiny Eggs and do not appear to be explosive. In Banana Storm, Ukikis may sometimes throw these instead of bananas, which Mario or Luigi must avoid. In Coin Collection, Mario or Luigi must avoid the Spinies while riding on a cloud; failing to do so will cause him to fall off.

The game also includes frozen variants called Ice Spinies, which appear to be flat chunks of ice with large, sharp icicles growing from the top surface. They can be briefly found in the background of Freeze Mountain during the game's campaign, where they are avoided while descending the mountain. Like red and green Spinies, they only make a significant appearance in the Mush Mode versions of Stage 4-4: Rendezvous on Ice, and Stage 4-4EX: Midnight Drive. Like the red and green Spinies, they come in two speeds, and stepping on Ice Spinies will make them to explode, causing the dance meter to drop significantly.
