Buy Grow a Garden Hydra
The Hydra is a Divine pet in Roblox Grow a Garden. It came out on November 1, 2025, during the Safari Harvest Event. This pale green and yellow dragon has three heads, sharp teeth, bright yellow eyes, and a long tail with spikes on its body.
The Hydra has two passive abilities. With Three-Headed, it ages itself up by 1, hatches an egg, and puts the Terran mutation on a random fruit. If it cannot do one of these actions, it cannot do the others. Other pets cannot mimic or refresh this ability. With Earth Deity, selling a Terran fruit gives a chance for one of that fruit's mutations to spread to another fruit in your garden.
The Terran mutation boosts a crop's value by a 75x multiplier, so the Hydra helps players earn more from their harvests. It also hatches eggs on its own, which grows your pet collection over time. The Hydra has a huge Hunger stat of 333,333, so it works well for long play sessions.
In the game, the Hydra comes from tier 47 of the Season 2 Season Pass. It cannot be hatched from the Safari Egg.
