Squeebl

It is currently unknown when squeebls were first domesticated to be an aquatic pet. But many theorize they were first used to symbolize world adventuring among the upper class; and have since become a popular staple in all kinds of households due to their simple care instructions, ability to survive without food, and cute size. Squeebls produce a thick, black ink that was used for maps, but can also be re-consumed by the squeebl itself to darken it's pigment; without this ink, these jelly creatures will fade into a transparent gray. Other inks, however, can transform these best-selling creatures into all kinds of vivid colors.
