Meep are parasitic animals which live on Morps. During the bird stage, they take the form of little worms which live inside the bird's digestive tract. Once the bird transforms into a fish and takes to the water, the Meeps will swim out of the Morp's mouth. They metamorphose into a form which is similar to an eel. and swim alongside the Morp, feeding off its dropped food, shed scales and other detritus. Once the Morp lays an egg, the Meeps will lay their own eggs on the surface of the Morp egg. The baby Meeps will hatch before the Morp does, and will proceed to burrow into the Morp egg, parasitising it before it even hatches.
