The Ocean is the tenth zone released in the game, in version 2.0.0 on the 14th of April 2022. It is the first Ocean Zoo zone, with the player being required to accumulate distance to upgrade habitats. It is unlocked when the player reaches Savannah 4 in the Sky Zoo, along with the Ocean Zoo. It contains the new mechanic O², where the player must collect bubbles in order to fill up their O² meter. If the player's O² meter runs out, the screen will begin to fade to black, and the player will either die by crashing into an obstacle that they cannot see, or be forced to end the run. Crabs also act as an obstacle, moving side-to-side and obstructing the player's path. Lastly, kelp is introduced, which slows the player down and hides any wild animals passing through. Like all other Ocean Zoo zones, it can only be played twice every 6 hours to begin with, with some animal upgrades reducing this slightly. Home to Clownfish, Crabs, Squid, Sharks, Manta Rays, Blue Whales, Dolphins, Trout, Swordfish, Eels, and Octopuses.
