The official description counts 20 biomes across 2 worlds. World 2 adds 10 biomes, about 80 pets, new bosses, barn skins, and a second barn. The Galaxy Explorer badge calls World 2 space. The Black Hole badge calls the Black Hole the last biome.
Player guides name World 1 as Earth and World 2 as Galaxy, and they publish a recommended Speed for each zone. Those numbers are targets to aim for before you walk in. If the portal on your server shows a different figure, trust the portal.
A 200 billion figure is the reported World 2 unlock. Video mentions of 300 billion, 25 trillion, and 50 trillion match later zone rows, especially Moon Base at 300 billion and Ocean Planet at 50 trillion. They are not competing prices for the same door.

World 2
Unlock is reported at 200 billion Speed. Scout a new zone once without a cage, then steal.
| Zone | Recommended Speed |
|---|---|
| Moon Base | 300 billion |
| Red Planet | 2.5 trillion |
| Ocean Planet | 50 trillion |
| Crystal Planet | 1.6 QA |
| Sun Planet | 37 QA |
| Shadow Planet | 730 QA |
| Toxic Planet | 29 QI |
| Storm Planet | 320 QI |
| Ancient Planet | 5.5 SX |
| Black Hole Zone | 126 SX |
In that table, K is thousand, QA is quadrillion, QI is quintillion, and SX is sextillion.
Official copy names Moon, Ocean, Crystal, Shadow, Storm, and the Black Hole, and says there are more. The longer names above are the zone-guide names for those places plus Red Planet, Sun Planet, Toxic Planet, and Ancient Planet. Four World 1 names beyond the official examples are likewise from that same zone list.
How to move up
Stay in a zone until you can return more than one cage. Then train to the next row. Do not carry a cage on your first visit to Shadow, Storm, or the Black Hole. Each named zone has its own map entry.
