Hello, 3D World!

Hello, 3D World! is the third course in the Story Mode of Super Mario Maker 2. It is set in the ground theme for the main area and the underground theme for the sub-area, as well as in the Super Mario 3D World style. It is posted by Lonely Farmer, and has a difficulty rating of 1/4 stars.

Layout
The level begins with a Stingby and a Piranha Plant further down. Another Stingby appears next to a Tree containing a Super Mushroom, along with a Goomba just ahead and a Big Piranha Plant next to a tree containing a Super Bell. The path splits from here; Mario can either head left to break some Brick Blocks to enter a Warp Pipe featuring an underground section with Big Goombas, or continue on the main path, which features a Big Piranha Plant guarding a 10-Coin. Both paths lead to the Checkpoint Flag, where Mario must navigate more Piranha Plants via an ! Block, then climb a Tree leading to yet another ! Block right next to a 30-Coin and some more Stingbies. After a brief slope, one more ! Block appears just before the Goal Pole.

Description
"I've planted all these cute Trees in my garden. Would someone try reaching the goal by climbing Trees with ↑? I haven't weeded the garden in a while, but if the Piranha Plants give you trouble, just stomp them into the dirt."
