How to get Cosmic Skeleton Boss
Reach about 700M Speed and travel to the Cosmic biome 🪐. Wait until the Cosmic Skeleton guardian is asleep, grab the Cosmic Skeleton Boss Egg from the nest and run back to your pen before you get caught. Nests reset every 5 minutes, and bigger eggs are worth more but make you slower — so bring extra Speed.
