Brontosaurus

The Brontosaurus is a Mythical pet from the Prehistoric Event, and its obtainment is genuinely punishing: it dropped from the Dinosaur Egg at just a 1% chance, with the DNA Converter as the only alternative path. A 1% hatch means most players burned through stacks of eggs without seeing one, so simply owning a Bronto signals either deep grinding or a lot of luck during the event.

What sells it for a farming build is the ability listed right on the row, Giant Incubator. Pets that influence incubation and egg-hatching are some of the most valuable economy enablers in the game, because they compound: faster or better hatches mean more pets, which means more passive income across your whole garden. A pet that accelerates your egg pipeline does not just earn its slot, it improves every future pull.

For a serious team, that makes the Brontosaurus a legitimate keep rather than a shelf trophy. The brutal 1% odds keep it scarce and trade-valuable, while Giant Incubator gives it real mechanical purpose beyond Mythical bragging rights. If you hatched one, it deserves serious consideration in your active lineup, especially during heavy egg-opening sessions.
