Steal An Egg Update 4 adds a biome that never looks the same twice: the new Angels & Demons Biome flips between an Angels form, a Demons form and a fused form every time the day-night cycle shifts, and the eggs you can steal change right along with it. Tucked inside that same biome is a Secret Fusion Room you can only reach with a bit of environmental puzzle-solving, plus a brand-new Luminous Egg that replaces the old Monster Egg. Between the biome, the fusion mechanic and the new egg, this update adds 28 pets in total. Here is everything currently confirmed about Update 4.
Update 4 needs 20B Speed to enter the new Angels & Demons Biome, which alternates between an Angels form, a Demons form and a fused guardian on the day-night cycle and adds 16 new pets (8 Light, 8 Dark). Inside that biome is a hidden Secret Fusion Room, reached by jumping into the waterfall (or lava, in the Demons form) that faces the entrance gate, place a Divine/Eternal Light pet and a Divine/Eternal Dark pet in the glow to fuse them into a new egg. Separately, the new Luminous Egg replaces the Monster Egg in the shop and adds 6 pets plus 6 Luminous Re-roll forms, each Re-roll landing at a 1% rate.
New Angels & Demons Biome
The headline feature of Update 4 is a biome that does not sit still. Every time the day-night cycle shifts, the zone can turn into the Angels Biome, the Demons Biome, or a fused version of both, and the eggs available to steal change to match. The original guardian changes with it too, transforming into a half-angel, half-demon hybrid once the fusion form is active.
The minimum Speed requirement to enter the new zone is 20B. As with every other biome, that number is only the entry gate, if you are chasing the rarer eggs in this area, your actual Speed usually needs to sit well above the recommended minimum to make it back out safely.

All Light Pets (Angels Biome)
The new zone features 16 pets in total, split evenly between its two forms. The 8 Light pets below hatch from Angels Biome eggs, so you will need to catch the biome in its Angels form or the fused form to collect them all.

How to Enter the Secret Fusion Room
You may have already heard rumors about the Secret Shrine, but its exact location is not immediately obvious. In fact, it is hidden inside the new biome.
Travel to the New Biome
Head to the Angels & Demons Biome first. You need to be inside this zone to find the Secret Shrine.
Find the Right Waterfall (or Lava Stream)
If the area is currently in its Angels form, head toward the angel guardian and look for several waterfalls. The one directly facing the entrance gate is the way into the Secret Shrine. If the area is in its Demons form, those same waterfalls turn into lava, but the entrance stays in the same spot.
Check the Landmark Direction
If you are unsure which waterfall or lava stream is correct, compare the landmarks. The landmark near the Secret Shrine faces a different direction than the others nearby, which is the giveaway.
Jump Into the Stream
Stand under the correct waterfall or lava stream and press space to jump. This drops you into the Secret Fusion Room.
Place a Light Pet and a Dark Pet
Place a Light-type Divine or Eternal pet in the yellow glow, and a Dark-type Divine or Eternal pet in the red glow. Once the fusion completes, you have a chance to receive one of several different egg types.

FAQ
What is included in Steal An Egg Update 4?
Update 4 adds the new Angels & Demons Biome, a hidden Secret Fusion Room inside that biome, and the Luminous Egg shop item, which together bring 28 new pets into the game.
What Speed do I need for the Angels & Demons Biome?
The listed minimum is 20B Speed. As with other biomes, you generally want a Speed cushion above that minimum before you try to steal the rarer eggs and make it back safely.
How many new pets does Update 4 add?
28 in total: 16 from the Angels & Demons Biome itself (8 Light, 8 Dark), plus 12 from the new Luminous Egg (6 base pets and 6 Luminous Re-roll forms).
Which pets can I use in the Secret Fusion Room?
Only Divine or Eternal-rarity pets. You need one Light-type Divine or Eternal pet for the yellow glow and one Dark-type Divine or Eternal pet for the red glow.
How rare is a Luminous Re-roll?
Every time you open a Luminous Egg, there is a 1% chance that the pet you hatch comes out as its Luminous form instead of the standard version. It is a re-roll on the result, not a separate pull.
