What is Leviathan worth?

Leviathan's money value is $220K/s at base weight with no mutation, and its rarity score is 64 (available). A mutation multiplies that value, up to $770K/s with Rainbow (x3.5); several mutations add up, and a heavier Leviathan is worth more.

Pets worth about the same: Flame Sprite ($225K/s), Light Dove ($225K/s), Riftwing ($220K/s), Nibbles #013 ($185K/s).
