Solaris Egg location and luck

Where the Solaris Egg spawns

1. Waterfall cave. Inside the cave behind the big waterfall, behind the crystals and on the raised platforms; also just outside the cave entrance.
2. Giant Tree. On top of the tree and inside the cabin.
3. Grey Mountain. Follow the stream outside the cave to its end, keep left and enter the opening.
4. Desert. Inside the Pyramid first, then the Desert Temple, entered through the small pond next to the Pyramid.

Good to know

• Added with the Mutations update as the third Ethereal Egg.
• The game announces it when it spawns; the Eggo NPC also tells you whether it is up.
• It breaks 20 seconds after you pick it up, so bring your fastest pet.
• The Eternal Radar tracks it, but it rarely restocks.

What the Solaris Egg can hatch

Using the luck model described by two guides, this is the rarest pet each ranch luck level brings within reach in this egg. Rarer pets need more ranch luck; commoner pets stay possible.

Ranch luck needed for popular pets

• Horse (1 in 500K): ranch luck ×1 · $350/s
• Fox (1 in 21M): ranch luck ×1 · $1.2K/s
• Unicorn (1 in 1T): ranch luck ×4 · $30K/s
• Phoenix (1 in 30T): ranch luck ×100 · $100K/s
• Kitsune (1 in 1Qi): ranch luck ×3.33M · $90M/s

Guides from GameBoost and BloxB describe Hatch Luck as your ranch’s Hatch Luck multiplied by the egg’s base luck, with a pet only possible once that total reaches its “1 in N” figure. The game does not document this, and no source says how likely a pet is once you pass its threshold, so treat these numbers as a planning guide, not odds.
