From the Super Mario Wiki, the Mario encyclopedia
Treetop Fireballs is the eighteenth course in the Story Mode of Super Mario Maker 2. It is set in the snow theme and in the Super Mario 3D World style. It is posted by Veteran Carpenter, and has a difficulty rating of 1/4 stars.
The level begins with two Trees containing a Fire Flower and a coin, respectively. More Trees appear interspersed between Track Blocks and Fire Bros, with two Heavy Fire Bros appearing afterwards along with some Track Blocks leading to a Warp Pipe. In the next area, taller Trees with one containing a Super Bell and the rest containing Super Stars comprise a vertical section of the level with a few Big Piranha Plants, with another Warp Pipe not too long after. After one final Tree, Mario will be guided by a Track Block to the Goal Pole.
"I managed to plant some Trees, and they actually look pretty good. But I'm not sure how sturdy they are. Can someone try climbing all 12 of my Trees before clearing this course?"
