Selfisher is an enemy in Trials of Mana. It resembles a clam with two appendages sticking out, holding a wooden spoon in one.
When a spell or effect is used that transforms enemies, such as the Freya summon, the Selfisher is what they transform into.
It will always be a Level 1 foe, and is worth a mere 1 EXP and 1 Lucre.
