Sometimes Squink gets so scared that it inks itself, and in its frantic attempt to dash away it accidentally blots out an entire galaxy!
You can unlock skins for this Little Legend by purchasing a Little Legend Egg, which costs 490. Cracking open your egg will grant you a random tier-1 unlock from the pool of available skins, including their original skin. Obtaining a duplicate will upgrade your skin to the next tier, up to tier 3, at which point the skin is removed from the reward pool.
During development it was known as Dark Star Squid.
