The Sky Bison is a Tier 4 flying herbivore added to Creatures of Sonaria as part of the COS X ATLA NETFLIX: Appa’s Journey collaboration, which arrived alongside the second week of the Land, Sea, Sky event. It is a limited-time creature, so the way you obtain it is tied directly to a single in-game mission rather than the usual Star or Pass Point shop unlocks.
Quick answer: Join the game while the event is active and start the “Appa’s Journey” mission to unlock the Sky Bison. Complete that same mission to also earn the “Momo” plushie.
How to unlock the Sky Bison
The Sky Bison does not cost Stars, Pass Points, or Robux. It becomes available simply by beginning its dedicated mission while the collaboration is running, so the main requirement is logging in before the event ends.
Note: The Sky Bison is not offered in the Trial Creatures Shop, so there is no trial version to test before committing. Claiming it through the mission is the only route.
How to confirm it worked
Once you start “Appa’s Journey,” the Sky Bison is added to your account as an available creature for the limited window. Completing the full mission adds the “Momo” plushie to your inventory. If the creature is missing, the most common reason is that the event is no longer active, since both rewards are gated entirely by the live event period.
Sky Bison stats and abilities
The Sky Bison is a large, six-legged flier with no gender differences in appearance. It has thick beige fur with dark brown stripes, two upward-curving horns, and a wide paddle-shaped tail. Its kit leans on crowd control and support rather than raw damage.

Its active abilities include Area Wind Blast, which charges a condensed wind ball over six seconds and launches creatures upward on impact, and Speed Steal, which grants the user four stacks of a speed buff while applying a speed-reducing status to nearby creatures. Passive traits include Sonic Wings, letting it idle in flight without spending or regaining stamina, Broodwatcher for assisting other players’ egg gestation, and Frosty for winter survival. It also carries solid status resistances, with 80% Block Frostbite, 45% Block Bleed, 35% Block Injury, and 25% Block Burn.
Other creatures added in LSS Week 2
The Sky Bison arrived alongside several other additions in the same update, each obtained through a different route. If you are working through Week 2, these are the relevant unlock paths.
| Creature or item | How to get it |
|---|---|
| Sky Bison | Start the “Appa’s Journey” mission |
| Momo plushie | Complete the “Appa’s Journey” mission |
| Ulyri | Contribute to the Biome Restoration in the LSS event |
| Isolun | Robux Shop |
| Shiny Shoal palette, Gift of the Sea material | New LSS event cosmetics |
| Ulyri Pack | LSS premium bundle |
Because the Sky Bison and Momo are both limited-time rewards tied to the live collaboration, the safest approach is to start “Appa’s Journey” as soon as you log in and finish it before the event window closes. That single mission secures the flying herbivore and its companion plushie without spending any premium currency.
