How to Acquire
Aluminium Ore can be mined from the Aluminium Dragon or from one of the Turtle sisters, and can be rarely found in crates in the Hummingberg Region (Winter) which requires the Icebreaker Boat Upgrade.
After Stella picks up Summer, she will say that her dreams have been haunted by dragons. Stella will first be introduced to the Quartz Dragon, followed by the Aluminium Dragon.
The gameplay is the same for both Quartz and Aluminium. Summer will ask Stella if she'd like to start the activity once they are in the area, and then Stella will hop from place to place, mining the Aluminium off of the dragon's back.
