What is Mecha Chompa worth?
Mecha Chompa's money value is $600M/s at base weight with no mutation, and its rarity score is 256 (limited). A mutation multiplies that value, up to $2.1B/s with Rainbow (x3.5); several mutations add up, and a heavier Mecha Chompa is worth more.
Pets worth about the same: Ember Dragon ($600M/s), Luminous Abyss Shark ($600M/s), Oni Tiger ($600M/s), Skeletal Glyptodon ($550M/s).
There is no official value list: for a real offer, put it in the trade calculator, which tells you if the trade is a win, fair or a loss (W/F/L). Every pet's value: the value list.
