Birthday Leviathan guide

With a maximum of 380,000 kg, Birthday Leviathan ranks 40th of 1,059 documented fish by weight, and its documented weights run from a minimum of 200,000 kg through an average of 290,000 kg. The price per kilogram is only C$0.148, yet the average sale value reaches C$42,928, which ranks 49th of 1,038 fish. Base XP is 50,000.

It is a Limited fish from the 2nd Anniversary zone, which has 12 documented fish; the other 11 share its rarity, among them 2nd Birthday Balloon, Birthday Candle, Birthday Card, Birthday Cupcake, Birthday Floppy and Birthday Pinata. The wiki lists it as no longer obtainable, so this page is a reference entry. The bait is Cupcakes, and time, weather and season are not listed. The game's text reads "Even the void sends a card. This Leviathan surfaced smiling for Fisch's 2nd birthday, party hat and all."

Verdict: a colossal event fish whose weight and value both sit in the top 50 of the documented lists, best treated as a historical record.
