Wobbling logs are platforms that appear in Super Mario World 2: Yoshi's Island. Most often appearing in athletic-themed levels, each wobbling log is situated on a post that ends in a wooden stake. The log balances on this stake like a seesaw, and it rocks back and forth when a Yoshi is not on it; if a Yoshi stands on it, the log tips over until it topples, unless he is in the center. If the Yoshi directly touches the spike, it damages him, causing him to drop Baby Mario in the process. Wobbling log posts also sometimes have a different color like other posts, such as dark blue in cavern levels.

Single-segment wobbling logs also appear floating in wavy lava in Bigger Boo's Fort and Tap-Tap The Red Nose's Fort. Here, tilting them is simply used to make the player travel safely across the lava in the same direction.
