Rolling log

Rolling logs   (also parsed as Rolling Logs) are a type of wooden platform originating from Super Mario 64.

Super Mario 64 / Super Mario 64 DS
Rolling logs first appear in Super Mario 64 and Super Mario 64 DS. They are cylindrical wooden platforms that, when stood on, will roll over. The player must run along them or jump carefully to avoid falling off until they reach their destination on a set path. When the rolling logs are not stood on, they begin to roll back to their original positions. One appears in Lethal Lava Land and is the focus of the mission Red-Hot Log Rolling, and another is on Tall, Tall Mountain.

New Super Mario Bros.
Rolling logs return in New Super Mario Bros. In this game, they are stationary platforms whose purpose is to eventually drop the player off of them if stood on long enough. They only appear in the underground sections of World 6-3.

New Super Mario Bros. Wii
Rolling logs reappear in New Super Mario Bros. Wii, behaving the same as in New Super Mario Bros., though they are colored slightly differently and now produce creaking noises when stood on. They only appear in World 5-3.

New Super Mario Bros. U / New Super Mario Bros. U Deluxe
Rolling logs appear yet again in New Super Mario Bros. U and its remake. Their behavior is largely unchanged from its past 2D appearances, and they appear only in the level Bridge over Poisoned Waters, though they reprise their role in the challenge Poison-Swamp Scramble. Rolling logs are among the few objects that do not return in New Super Luigi U.
