What is Brontosaurus in Grow a Garden?
The Brontosaurus is a Mythical-tier pet introduced during the Prehistoric Event in Grow a Garden. It hatches exclusively from the Dinosaur Egg, which itself is a limited-time egg from the prehistoric update.
What makes Brontosaurus special is its Giant Incubator ability - it boosts the base size and weight of all pets hatched from eggs by 5-10% (capped at 30% total). This makes it one of the most valuable utility pets for players who hatch many pets.
