The Leech Hydroe is a strange lifeform resembling the Goolix, Waterwraith, and Plasm Wraith in concept, and one of the final creatures studied during Captain Olimar's Sparklium expedition onto PNF-404.
Description[]
The Leech Hydroe is a very small creature, only about the size of a standard Hocotatian. If the Wraiths, Goolix, and Leech Hydroe are apart of the same family, that would make this the smallest species of the four. Its body is slightly transparent and gelatinous, with no internal organs, skeleton, or cellular core visible. It has six simplified legs in a circular pattern, and a single antenna on its head.
It is a parasitic creature, described by Olimar to have taken control of a plant to drain its nutriants. The host (in Olimar's report, it being the Berserk Leech Hydroe) must then venture out in search for more food to feed both itself and the Leech Hydroe.
While hardly mentioned, it was described to have enough intelligence to recognize Olimar as a threat, and quickly retreated shortly after.
