Update 16, the Bloodmoon update, is dated March 8, 2026 on the update history. A boss guide dates the same update March 9, 2026. Use March 8 as the history date and treat March 9 as a one-day disagreement, not a second patch.
What the update added
- Bloodmoon weather, with Bloodmoon Grapes on the map.
- A boss catch that needs at least two players.
- Bloodbound (2.5x) from feeding grapes. The feed is a chance.
- A spin wheel on the map during the event.
- Mutation Diffuser for $500,000.
- More Forgotten Depths pets, and admin-spawned Mythic eggs called out as rare.
Weather rows say a weather event lasts about 10 minutes. The update video says Bloodmoon shows up about every 2 hours, and that the wheel can be spun once a day for free. Those two timings can both be true (a short weather window on a longer cycle, plus a daily wheel), but they are not the same sentence. Check the timer you see in game.
Boss catches
The catch bar does not move until a second player also lassos. A written guide says everyone who helped keeps the pet, and that bosses cannot be stolen. The update video describes a failed attempt because the player was not the best participant on that catch. If you are helping, confirm the reward text before you leave the animal.
| Name in guides | Where it is listed |
|---|---|
| King Seal | Starting Island |
| Colossal Mammoth | Snow Island |
| King Kraken | Forgotten Depths |
| Boss Hydra | Near water during Bloodmoon |
| Skeleton Hydra | Dragon Island, on the four-boss table |
Boss Hydra and Skeleton Hydra may be one animal under two writeups. Albino King Crocken is a video name with no island on the table. Ride something if you have a mount; the video's practical tip is that other players will reach a spawn first if you run.
A later video says a Boss Catcher stat on a lasso, obtained on Bee Island or Cave Island, lets you catch boss-category pets alone. That stat is not in the March lasso table. If your lasso shows it, you can test a solo bar. If it does not, bring a second player.
Grapes and the wheel
Pick up grape clusters and feed them to the pen pet you care about. Remove or hide a 1.1x mutation first only if the machine button matches what you want; see the items pages for the remove-versus-hide conflict.
The wheel is a physical object during Bloodmoon. One guide says one spin per weather appearance, with grapes, Bloodmoon Lucky Blocks, and coins. The video says one free spin a day and mentions a Bloodmoon Stag as a rare wheel result. Spin when it is available. Do not assume a second spin in the same weather.
Boss rewards include Bloodmoon Lucky Blocks. Those blocks are a fixed pool. Opening them during Aurora does not help.
