If you want to summon Mama Quilla's pets, Diggy needs to climb the peaks of the nearby mountains in the location "Astral Planets" and light the star constellations from there.
The first constellation is on top of the "Cat Peak", so let's climb it!
Diggy will need to use the following lever in order to proceed on the other side:
Be careful, as Diggy goes on, he will need to move stone obstacles:
Right on top of the "Cat Peak", please get the matches and light up the sacrificial fire with them. Then stand on top of the symbol which Mama Quilla's Priestess drew with chalk and the smoke will show you the way of the sacrifice:
Now let's follow the way of the sacrifice and light the constellations with your touch. Don't worry, nothing bad will happen to you. Only if you stray into the darkness:
Once you light up the constellation, you will be able to see the path to the stars:
Get the Astral Cat:
Good job! Now you can climb the peak of the Silver Hill, the second constellation is above it. Let's take a shortcut through the cave:
Since the miners are not kind of fond of the Mama Quilla's Priestess, please get her to the peak of the hill to the red flower without the miners spotting her. In order to do so, please drag the bucket of water here:
Now, push the barrel with the Priestess all the way to the top of the mountain peak to the red flower.
You will need to use the crane but due to the fact that it's not working with no cargo, please tie the barrel to it first:
Use this pattern three more times:
Push the barrel with the Priestess to the red flower:
Climb up to the Priestess:
Get the matches and light up the sacrificial fire with them. Then stand on top of the symbol which Mama Quilla's Priestess drew with chalk and the smoke will show you the way of the sacrifice:
Light up the constellation and get the Astral Llama:
Return to the location "City of Gods" and talk to Mama Quilla:
