Bumper (Super Mario series)
From the Super Mario Wiki
Bumpers are objects that appear in New Super Mario Bros., Super Mario Maker (in version 1.30 or later), Super Mario Maker for Nintendo 3DS, and Super Mario Maker 2. They serve the same purpose in all appearances so far, bouncing Mario away when he makes contact with them.
New Super Mario Bros.
In New Super Mario Bros., they appear in the underwater sections of World 1-A and World 8-3. They appear as translucent yellow bubbles with an eight-spoked plantlike symbol on or inside them. Bumpers will bounce Mario in the opposite of the direction he ran into them from.
Super Mario Maker / Super Mario Maker for Nintendo 3DS
In Super Mario Maker (v1.30 or later) and Super Mario Maker for Nintendo 3DS, Bumpers can be created by shaking a Grinder in editing mode. Their appearance now resembles that of a torus with eyes. When Mario jumps on one from above, it can bounce him higher similar to trampolines and Note Blocks; if Mario bumps into one from the side or below, it bounces Mario away. Enemies and objects are not affected by Bumpers and will freely pass through them.
In the Super Mario Bros. game style, Bumpers are striped light and dark green, with eyes similar to that of Mr. Eraser. In the Super Mario Bros. 3 style, they are checkered green and white similar to the Jump Blocks from New Super Mario Bros. Wii, with the same type of eyes. In the Super Mario World style, they are white with pink diamonds and beady eyes. In the New Super Mario Bros. U style, they retain the beady eyes and are yellow with an orange star pattern, resembling Lemmy's rubber balls from the New Super Mario Bros. series.
Super Mario Maker 2
Bumpers reappear in Super Mario Maker 2 as objects under the Gizmos category, and act and look just like they did back in Super Mario Maker and its 3DS port. They are absent in the Super Mario 3D World game style.
