My Friend Mr. Bumper!
From the Super Mario Wiki
My Friend Mr. Bumper! is Mr. Eraser's second official course in Super Mario Maker, released on December 24, 2015. It is set in the ground theme for its main area and in the underground theme for its sub area, as well as in the Super Mario Bros. 3 game style.
The level begins with a long series of Bumpers that eventually leads to a warp pipe, which in turn leads to a Checkpoint Flag, some Super Leaves, and another warp pipe. What follows is an even longer series of Bumpers, this time with Bumpers on tracks. After quite a while, the goal appears.
