Hidden Hills

Hidden Hills is the true final world of Yoshi's Crafted World. It is a colorful world filled with challenging levels. All of the levels in the world do not contain Check Points or a flip side; it is additionally the only world in the game to be completely optional. It is unlocked after completing Shadowville and connects to Outer Orbit. It is made up of four levels: Rough Rolling, Under Siege, Floppin' and Poppin', and Kamek Kerfuffle. Each level uses mechanics from previous levels of the game.

Unlike most worlds, Hidden Hills is home to two Blockafellers: a regular Blockafeller who can be accessed after completing the third level and gives the player craft requests, and a Torque. Unlike most Torques, who require a certain number of Smiley Flowers before opening up a boss level, this one waits before each level, requiring a number of flowers to unlock the next level. Thirty Smiley Flowers each are needed to unlock the first three levels, while fifty flowers are required to unlock the boss level. Due to this, a total of one-hundred-and-forty Smiley Flowers are required to access the entire world.

After the final level is completed, the player earns the Kamek costume. The Torque also congratulates Yoshi before becoming inactive once again, this time asking for 317 Smiley Flowers, the number left to be collected throughout the game. If this is accomplished, the player is rewarded the Sundream Stone costume.
