What is Gigantus worth?
Gigantus's money value is $1B/s at base weight with no mutation, and its rarity score is 563 (limited). A mutation multiplies that value, up to $3.5B/s with Rainbow (x3.5); several mutations add up, and a heavier Gigantus is worth more.
Pets worth about the same: Skeleton Horse ($1.3B/s), Archdemon Dragon ($1.25B/s), Mecha Krakenoid ($1B/s), Rhinobear ($1B/s).
