SV Snaggerjag appears as the top half of a stout, green-skinned humanoid Yo-kai emerging from a wooden sailboat. He has curly black hair, bushy eyebrows, a beard and mustache, and glaring yellow eyes, with a frowning mouth full of sharp teeth. He wears an orange happi with green accents and a white wave pattern, and a fishing rod with a dangling line and hook is attached to the top of his head, with a headband tied at the base. His boat flies a purple square rig sail with the kanji for "treasure" (Japanese: 宝 Takara) inside a circle painted in white. His hair also goes up on the left and right which it curves to look like demon horns.
His befriendable form, however, loses most of his boss form's features, losing the kanji on his sail, his hull is smaller, his facial hair is reduced to a soul patch, and his eyebrows loses the horn feature on his boss form.
SV Snaggerjag is stiff and doesn't like it when people or Yo-kai mess around in the pond because he is afraid it will scare the fish away.

He brings bad luck to anglers and can command the fish that live in his lake.

After his defeat, he calmly asks the player to not to cause splashes again, as they disturb the fishes.

SV Snaggerjag can swing his hook to one Yo-kai in order to damage him. However, his most used move, Takin' It OuT, has him to fish out some Koi fish Yo-kai in order to assist him in battle. Up to two fish can stand at his sides in battle, and their color determines their behaviour in combat:
- Green fish, Meditatum, can restore him some health.
- Blue fish, Shuter, will launch water attacks on one Yo-kai.
- Red fish, Grumpus, does physical attacks.
If two fish are along him at the same time, he will charge and launch a Soultimate, A Fisher's Life, which damages all three of the front row Yo-kai, so the player should avoid keeping both fish in battle for long.
