Cog (obstacle)

Cogs (also known as gears) are obstacles in some Mario platformers. They have the ability to push the player off if one tries to climb one.

Yoshi's Story
Cogs appeared in Yoshi's Story in the Mecha Castle. They are wooden and can only make a Yoshi lose a life if the player rushes to two of them and they are spinning towards each other.

New Super Mario Bros. Wii
In New Super Mario Bros. Wii, cogs can be found in. If the player remains under one, they will be squished and will lose a life.

New Super Mario Bros. U
New Super Mario Bros. U brings back cogs in Crushing-Cogs Tower. They serve as platforms so the player can reach the top of the tower to fight Boom Boom.

New Super Luigi U
Cogs reappear in the New Super Mario Bros. U expansion, New Super Luigi U, in Crushing-Cogs Tower's equivalent, Flame-Gear Tower, and Hot Cogs.
