Abilities
The Fresh Fish Head comes with Comeback as the primary ability, which, being exclusive to the main slot of Headgear, prevents the wearer from also having Last-Ditch Effort, Opening Gambit, or Tenacity. As a 2-star item, the Fresh Fish Head comes with two additional slots for secondary abilities, which may be increased to a maximum of three slots with a Super Sea Snail for each slot. Since it is made by the amiibo gear brand, it has equal chances to roll any secondary ability.
