Capfish
From Starfy Wiki
Capfish are Coddies who have Glowing Mushrooms growing out of their heads, because of this they are able to swim through the poisoned swamps of Sogwood Forest since the mushrooms absorb the poison. During a mini-game in Sogwood Forest Starfy uses these fish to find Old Man Vern's lost treasure.
Toy description
"Word is this guy's just a Coddie with a mushroom growing out of his head. These fish have tons of names. At least they come when you call them!"
Trivia
- On The Moe Show in The Legendary Starfy, Herman tells Moe that he's heard about a rare type of Coddie (the Capfish) in Sogwood Forest, but fears that his own Coddies would become jealous if he ever acquired one.
