Bronto earns 1.5M/s base income in Steal An Egg, the #90 highest-earning of the 177 pets tracked. It is a Cosmic pet hatched from the Bronto Egg in the Prehistoric biome. Hatching it also pays out +300k Speed, $150m. The egg takes 11m to hatch. Income here is the base rate as of 19 October 2026; a color mutation and a bigger size roll multiply it, see the table below or the income calculator. Steal An Egg has no trade window, pets can only be gifted one way, so anyone offering to “trade” for your Bronto is asking you to give it away.
