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 the songs "In the Whirlpool" and "Step by Step," Spinies sometimes appear in place of an arrow, and they look like metallic spheres with spikes and have black rims, essentially appearing to be mines. If the player steps on a Spiny, it explodes (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.

Another form of Spinies appears in the minigames Banana Storm and Coin Collection; these Spinies resemble orange Spiny Eggs and do not appear to be explosive. In Banana Storm, Ukikis may sometimes throw these instead of bananas, the former of 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 causes 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 make a significant appearance only in the Mush Mode versions of the songs "Rendezvous on Ice" and "Midnight Drive." Like the red and green Spinies, they come in two speeds, and stepping on Ice Spinies makes them explode, causing the dance meter to drop significantly.
