What is T-Rex worth?

T-Rex's money value is $25M/s at base weight with no mutation, and its rarity score is 128 (available). A mutation multiplies that value, up to $87.5M/s with Rainbow (x3.5); several mutations add up, and a heavier T-Rex is worth more.

Pets worth about the same: Shadow Dragon ($25M/s), Spiderpig ($25M/s), Bomboclat Crocolat ($20M/s), Rhinotaur ($17.5M/s).
