What the current source confirms
- World 2 is described as adding 10 new biomes and 80 new pets.
- The Dinosaur Era Cage is described as containing 12 pets.
- The game advertises a free Legendary for joining the Snail Riders community.
- Pet names, odds, speed values and event availability can change inside the live game.
How to build a trustworthy list
Record the cage name, world, biome, pet name, rarity label and the date you opened it. Keep “officially advertised”, “seen in game” and “reported by players” in separate columns. That prevents a World 2 teaser, a pet screenshot and an old event reward from becoming one misleading list.
The official game page is the source for the advertised Legendary community route. Use the game itself to verify whether the route is still active before joining a group or chasing a reward.
