History of Exotic fish

The Exotic fish are four rare catches from Season of the Deep's fishing ponds: Kheprian Axehead, Whispering Mothcarp, Vexing Placoderm and Aeonian Alpha-Betta. Three are tied to the Wicked Implement scout rifle. Deposit them in the H.E.L.M. aquarium for an Exotic reward. Catching all four unlocks the Pond Pals emblem.
