How to get Cosmic Skeleton Boss
Head to Cosmic — its speed requirement is 700M, the Speed you need to outrun the guardian on the way back (the speed calculator shows how long that takes), find the Cosmic Skeleton Boss Egg in a nest, get past the Cosmic Skeleton guarding it, and carry it back to your pen to hatch. Bigger eggs hatch into more valuable pets but slow you down.
