Jewel-Block Cave

Jewel-Block Cave is a course in Petal Isles in Super Mario Bros. Wonder. It has a difficulty of three stars and contains two Wonder Seeds. It is primarily designed around the use of the Drill form, with most elements in the stage interacting with it. In the Nintendo Live demo shown during PAX West 2023, it is shown to be located in Pipe-Rock Plateau, though it is replaced by Here Come the Hoppos in the Super Mario Bros. Wonder Direct.

Layout
The level takes place in a cavern full of Jewel-Blocks, Konks, and Spinies walking on the ceiling. The player starts near a Konk in a recess in the ceiling, with a wide Jewel-Block below and a ? Block above it containing a Drill Mushroom. Inmediately after, they will encounter a Spiny, more Jewel-Blocks (including one with a Talking Flower trapped inside) and another Konk. After a small tunnel accessible only in Drill form leading into an alcove with a few coins, there will be a segment with Spinies and Jewel-Blocks above small pits, and then another Drill-exclusive tunnel, leading to a Warp Pipe. Through it is a side room featuring coins, flower coins, a Talking Flower and a 1-Up Mushroom. If the player doesn't take the Warp Pipe, they will have to avoid three Konks and several pits. Both paths rejoin right before the Checkpoint Flag.

Past the checkpoint, cyan, upwards-facing Konks are introduced, along with beacons in the ceiling. Past another Konk, a Wonder Flower can be found inside a Jewel-Block. Touching it will trigger the course's Wonder Effect, which will create blue blocks that wall the player into a vertical shaft and summon a screen-sized Konk above. The Konk will slam down periodically, breaking Jewel-Blocks in its way, but will stagger after breaking stone blocks. The Wonder Seed is found at the bottom of the shaft, encased in a Jewel-Block. A Warp Pipe will take the player to the next part of the level, featuring a horizontal hallway with both downwards- and upwards-facing Konks on either side of a bridge of Jewel-Blocks. At the end is another Warp Pipe, leading to the outside of the cavern, with one last Spiny, a staircase of Jewel-Blocks and the Goal Pole, where the second Wonder Seed is awarded.
