Inktober Monstrosities: H for Hippocamp

The Hippocamp, or Hippocampus (not to be confused with the latin name for the common sea horse, or the part of the brain integral in navigation and memory) is a classic, both in real world mythology and in the world of D&D.

Half horse with webbed hooves, half fish, the hippocamp is obviously the result of someone taking the description of a common sea horse a tad too litteraly. They are part of both Etruscan, Phoenician and Greek mythology, among other things described as the horses of Poseidon, god of the sea. They are a common motif on fountains and heraldic designs throughout the world.

In D&D they are usually called Hippocampus, and they first appeared in the original Monster Manual, and then later throughout 2nd and 3rd edition. 5th edition does have stats for a Giant Sea Horse, but no mention is made there to it having hooves, so that is clearly just an oversized version of the common sea horse.
