Character: coach sam (zourik)
Coach Sam is a original Samurott character created by Zourik. His first appearance is in a set of images, who went on to create the comic Setting Up the Bait.
He is a male anthro Samurott, his entire body is dark blue, he has a slightly lighter shade of blue countershading on his torso.
His head is surmounted by a very large shell ending in a point that looks like a horn. On his face, his eyebrows, mustache, sideburns and goatee are white. He also has a small red nose.
His toes and the tips of his fingers are black.
He is also often depicted wearing an open red jacket.
As his name suggests, Coach Sam is a swimming coach. His name is simply a contraction of the name of his species.
Finally, among his students (who are also Water-type Pokémon): a Vaporeon, a Dewott, a Marshtomp and a Golduck...
There's one: Nathan, a Buizel who is very, very often pictured with him.
