1. For completing this request, you can get Powered-Up Cut as a reward.
2. Use Rock Smash west of the Pokemon Center to access the Hot Springs.
3. Build a Mossy Hot Spring by using Leafage on the mossy tiles, specifically the ones near the edge of the hot springs.
4. Create a path for Torkoal by adding steps or fixing the path ahead. Clear anything that would break the path.
5. If Torkoal gets tired, keep talking to them to resume their walk toward the Pokemon Center.
6. Build the Bread Oven. You need 2 Stones, 2 Small Logs, and 4 Volcanic Ash to build it. All the materials can be sourced from the area. If you are unfamiliar with Volcanic Ash, it is the black blocks surrounding the area that can be broken with Rock Smash.
7. Bake three Wheat to make Simple Bread. You can get this crop at the farm area near the Pokemon Center.
8. Eat the bread and you will learn Powered-Up Cut. Climb up the crates and barrels and use the Powered-Up Cut to free Chef Dente.
