Volcanic sits in one place only
It shows up deep inside the Dragon's Lair on Volcano Island, and the Eternal Radar does not point at it, so the radar trick other players use won't help here.
Why the egg you want keeps slipping away
An Ethereal Egg in Ride A Pet does not wait for you. , , and . This page skips the route: you choose the egg, , and .
The other three share a small list of spawns
Black Hole, Cherub and Solaris appear at the same handful of spots: the Giant Tree, the waterfall cave and the ancient pyramid among them. Whoever arrives first gets it.
Solaris breaks if nobody reaches it
It is the newest of the four and it doesn't sit around. Miss the window and the egg is gone, so you begin the loop again on the next server.
The hatch runs on the game's own odds
Picking the egg picks the pool it hatches from. The roll inside that pool is the game's, shown next to the result, so a rare mount stays a rare mount.
The mount lands in your nest
You type the Roblox username, the page finds the account and runs one security check, then the mount goes to that player's nest. It works in the browser on a phone, a tablet or a computer, in eleven languages.
The four eggs, and the spots where players chase them
One screen to keep: the Ethereal line on the left, the spots they are hunted in on the right.
