Hither Thither Hill
The first section of the level has two Warp Pipes to the underground and a large windmill. The windmill's blades block the entrance to it. Mario must use Paperize to paste a Fan sticker on a stump to cause a huge whirlwind that causes the blades to move. Inside the windmill, there are four yellow blocks with numbers on them.
The next area is an enclosed garden that ends with a dead end. Many stickers are pasted behind the fence, along with another Warp Pipe to the underground.
The undergroud complex is infested with Buzzy Beetles. A Heart Block can be found to the left of a seemingly incomplete pipe. If Mario takes an alternate route, he is able to cross a few cave platforms to find the Pipe scrap. This scrap can be pasted into the pink nothingness beside the Heart Block.
Inside the enclosed garden, a bawling Toad can be found. If Mario talks to him, the Toad will request Mario to escort him back to Decalburg. The Toad must not touch any other enemy, or he will run back to the garden. Successfully escorting the Toad will make him reveal the windmill code - 4123.
When this code is entered, the windmill will reveal a pipe to the cave platforms to allow Mario to get the Pipe scrap. After returning the pipe scrap, the pipe can be entered to find an enclosed room where the Big Buzzy Beetle boss is fought. After the boss, an HP-Up Heart is earned. A pipe to the ground can then be found, which leads to a hidden garden with the Comet Piece.
The outline for the door is located at the cliff in the secret garden. The chamber that the door reveals includes the Matches Thing.
Sticker upgrade spots
Immediately at the beginning of the second map is a hexagonal formation of flowers that can be bloomed using the hammer. The spot is above it.
Appearance in the Super Smash Bros. series
In Super Smash Bros. for Nintendo 3DS and Super Smash Bros. Ultimate, a stage based on the Paper Mario series called Paper Mario contains different variations within the stage, one of which is Hither Thither Hill. The battle takes place in the area with the windmill, which appears in the background along with the Warp Pipe. The Fan sticker (when used in Paper Mario: Sticker Star) can also be seen in the background, blowing strong winds that can have an effect on the players.
