Steal An Egg Biomes
Progression is Speed-gated: train on your treadmill to unlock deeper biomes with rarer egg pools. Event-bound locations can have an unknown entry rule. The documented gates and pools are independent-reference data: Sportskeeda's Speed guide supports the main gate sequence, and IGN's updated biomes table with TechWiser's Aug 30 list document the Titan Temple biome added with the Monster Update.
Light vs Darkness — Angels vs Demons
UnknownUpdate #4 now has both event-side labels in the biome registry. Demons is directly confirmed by live egg-spawn notifications; Angels, the 16 side-specific egg mappings, the two fusion outputs and Luminous Egg are documented by the official event identity plus community references. Entry Speed, map order, guardian, permanence and Light/Dark rules remain unknown for both; 20B is only a community recommendation.
