"Eels for Dinner" - Selma wants Plains Eels x3 from the Grassy Plains for dinner. An Apprentice Angler should have no trouble catching that!
Players who have purchased and completed the Origin Island downloadable content may require Giant Plains Eels x10 in exchange for Silver Lunares Coins. (through Pam)
TIP: The easiest way to catch Giant Plains Eelsis to use the Victory Fishing Rod while active in the Angler life, as the player will be able to catch five fish instead of three due to being active in the Angler life.
