Can't draw to save my life, but:
Mystick
Bug/Psychic
Small purple tick with an eye pattern on the 'blood' sack, they latch on to people/pokemon's heads and feed off their dreams. The eye pattern is actually blood vessels which can contract and expand to change the pattern to communicate, e.g. a 'closed' eye, an 'angry' eye, etc.
Evolves in to Fleamurr
Bug/Psychic
A giant pastel pink swollen levitating flea, with a small 'head' with pale white eyes and small mandibles. The abdomen or 'sack' bears the appearance of a large human brain, with two long flea hind legs dangling from the back where the brain stem would be that mimic its' appearance.
Mystick may ride on the Fleamurr, usually sitting on the front, giving the comical appearance of a brain with two 'eyes'. Partially based of a 'brain in a jar' and the Winter Lanterns from Bloodborne.
