- Sea area opens after you clear the land progression
- Outer space the stage that follows the sea
- Underground area arriving in a future update as Chapter 3
- Trash collection the action that drives every unlock

Prestige and what it does for you
Step
Prestige — also called Rebirth inside the game — lets you start over once you meet a certain condition. The payoff is that each reset unlocks further upgrades that were not available on your previous run. A prestige update also made upgrades that were once exclusive to Robux purchasers free for all players.
- Trigger your first rebirth doing this earns you the TIME TRAVELER badge
- Claim your new upgrades a fresh set of upgrades unlocks after each prestige
- Check for free upgrades upgrades that used to cost Robux are now obtainable without spending anything
Using badges to track your progress
Check
The game awards a badge each time you hit a major unlock. If you are unsure whether you have met a condition, your badge list is the quickest place to check.
- Cenozoic Era badge earned horses are unlocked
- Miocene Epoch Era badge earned gorillas are part of your crew
- Mesozoic Era badge earned dinosaurs have joined
- Turtles Don't Eat Plastics Silly badge earned the sea area is open
- I'm Above The World badge earned outer space is accessible
- TIME TRAVELER badge earned you have completed your first prestige
What to do when you are stuck
Tips
If the next area will not open, work through these checks before anything else.
- Check whether prestige is available and trigger it if it is
- Look through your upgrades for anything you have not collected yet, including the ones that used to cost Robux
