Minna de Awasete!
From the Super Mario Wiki
みんなであわせて！ (Minna de Awasete!, "Match Together!") is an official course in Course World in Super Mario Maker 2. It is the seventh level published by NintendoJP. It is set in the Super Mario 3D World style, in the snow theme for its main area and in the underground theme for its sub-area.
The level begins with a Clear Pipe leading to a Conveyor Belt. A few more Conveyor Belts follow, along with some Blinking Blocks acting as walls for one Conveyor Belt, and an ON/OFF Switch that must be triggered to deactivate some Spike Blocks and enter a Warp Pipe. In the next area, Mario must carry a Crate through two Clear Pipes while hitting ON/OFF Switch to toggle groups of Spike Blocks. At a third Clear Pipe, Mario must throw the Crate in before going after it, then long jump across and hit one more ON/OFF Switch to enter a Warp Pipe. Mario will then reach a Checkpoint Flag and must navigate Clear Pipes while paying attention to the timing of Blinking Blocks to enter yet another Warp Pipe. The next area has Mario using ON/OFF Switches to navigate rows of Spike Blocks and reach one final Warp Pipe. Mario must then use one more Conveyor Belt to reach groups of Blinking Blocks, then hit one more ON/OFF Switch to be led to the platform with the Goal Pole.
