Prehistoric Event

Introduced in Version 1.13.0 and catalogued as Standard Weather, the Prehistoric Event is one of Grow a Garden's larger themed content drops rather than a quick passing buff. Its dinosaur theming reshaped the meta around pets in particular, since it was the era that delivered prehistoric companions with standout utility. The headline addition was the Brontosaurus, a pet that grants increased weight on egg hatching, a genuinely powerful effect because pet stats scale with weight and a heavier hatch means stronger abilities from the very start.

For players, the strategic value of a Prehistoric Event lies in stocking up on its era-specific eggs and pets while they are obtainable. Weight-boosting and age-related pets like those tied to this event compound over time, so acquiring them early pays dividends across every later grind.

Because it is a structured event rather than a random weather roll, plan around it: prioritize hatching during the window, chase the dinosaur-themed lineup, and pair weight-gain pets with the Ostrich's age boost to push companions toward their strongest stat tiers. Event-locked content like this rarely returns unchanged, so treat each Prehistoric appearance as a limited collection opportunity.
