The below maps are color coded and show each dungeon layout.
An arrow indicates a 1-way trip only.

Key names are based on what the animal/object is, not Draak names, for the sake of clarity.

Spoilers ahead, of course. I would recommend going through each of these areas on your own at least once, for the experience, but it's your call!

Tunnels - map and overworld map location

The Great Lesson - map and overworld map location

(Note: Speak to Darktooth first and pay 20 shinies to open up the Great Lesson. If you choose not to travel there on that sun, then the location will appear on your map right below Darktooth to visit at your convenience)

(Note 2: All mural rooms except 6 and 7 in the first half of the Great Lesson contain well-hidden one-way passages that can be found by moving the cursor over the lower corners of each room. The pink arrows on the map indicate where these passages connect to)

Ant Colony - map and overworld map location

(Note: This location will only be revealed to you by the Allmother if you reach a decent level of compassion)

(Note 2: If you run out of energy or lose in the dance of destruction as an ant, then you will be allowed to return on another sun to attempt the dungeon again, with your overall progress saved)
