Spinies, known as Togezō (トゲゾー?) in Japan, are quadruped Koopas, first appearing in Super Mario Bros. They are often thrown by Lakitus in unlimited supplies, but can also be naturally occurring. Spinies appear in many Mario games like Super Mario Bros, Super Mario 64, New Super Mario Bros., New Super Mario Bros. Wii, Super Mario Galaxy and Super Mario Galaxy 2.
Spinies made a brief TV appearance in The Super Mario Bros. Super Show in the episode "Mario and the Red Baron Koopa". King Koopa had ordered Lakitu to throw several Spiny Eggs down to the people of Pasta Land, which hatched into Spinies, and terrorized the people for a short time. The Spinies seen in this episode were fairly similar to their game appearance.
A single Spiny later appeared in the continuation of the show. In The Adventures of Super Mario Bros. 3 episode "Life's Ruff", a Lakitu tossed a Spiny Egg next to a dog-turned Luigi, which hatched into a Spiny and bit Luigi. This Spiny looked much like the ones seen on The Super Mario Bros. Super Show!.
Spinies have appeared in other games including one of the games in the Mario Party series and made appearances in Super Smash Bros. Brawl, Paper Mario, Paper Mario: The Thousand-Year Door, Super Paper Mario, Mario & Luigi: Superstar Saga, Mario & Luigi: Partners In Time and Mario & Luigi: Bowser's Inside Story.
Spinies appeared in Dance Dance Revolution: Mario Mix, but the dance game also introduced Ice Spinies. Both the regular Spinies and the Ice version would make the Dance Meter go down when stepped upon. The Ice Spinies, however, were not Spinies at all and were simply a frozen piece of ice with sharp spikes on them.
Spinies are represented in the Mario Strikers series as an item: a huge, spinning, spiked shell. This shell will bounce off walls until it eventually hits a player. When it impacts with a character, it will explode, and possibly hit other players as well. If any players are hit, they will be stunned for a few seconds.
