How the eggs roll
Each biome has a fixed weight for each of its eight eggs, and every egg that spawns rolls on those weights. Angels & Demons is the exception: each egg cycle it becomes Angels, Demons or a mixed night first, and the mixed night shares the rarest eggs of both sides. Which pet is worth what is on the pets page, and the Speed to reach each biome on the biomes page.
Questions
What are the odds of the rarest egg in each biome?
They drop as the biomes get faster: Brr Brr Patapim in Forest is 1% (1 in 100), El Maja in Abyss Ocean 0.089%, and Royal Skywhale in Enchanted Forest 0.02% (1 in 5K).
Do luck boosts change these odds?
Server luck boosts shift the rolls towards rarer eggs by amounts set on the game's servers, so these are the base odds with no boost. The Lucky pass is for lucky blocks and fuse machines, not biome eggs.
How many eggs until I get it?
Nothing in the game's egg configs counts your misses, so treat every egg as a fresh roll. The calculator gives the eggs for a 50% and a 90% chance; past that, each extra egg is the same roll again.
