Merhogs are creatures that appear in Adventures of Sonic the Hedgehog. They are a species of aquatic Mobians that live underwater in Mertopia.



Merhogs appear as half-hedgehog, half-fish hybrids. They have the torso, arms and head of a hedgehog; their heads have hedgehog spines akin to Sonic's but with no spines down their backs. Below their waist, they have fish-like tails with scales. The Merhogs come in various pale colors consisting of green, pink, orange and yellow, with some deeper colors, like purple, for their belts or tails. The merhog queen as a red tail.

While Merhogs' physique look identical to one another, their queen is bigger, with a more human-like face and a large pointy nose.
