Buy Grow a Garden Rainbow Hydra
Description
The Rainbow Hydra is a Divine pet in Roblox Grow a Garden. It came out in the Safari Harvest Event on November 1st, 2025. It is a dragon-like pet with three heads. Each head has bright yellow eyes, sharp teeth, and a red tongue. Its body has spikes and a long tail that fades from pale green to dark green.
The Rainbow Hydra has two strong abilities. With Three-Headed, every 19 minutes and 50 seconds it ages itself up by 1, hatches an egg, and puts the Terran mutation on a fruit. As the pet gains weight, this cooldown drops to as low as 13 minutes and 20 seconds. The Terran mutation boosts a crop's value by 75 times. With Earth Deity, selling a Terran fruit gives a 14.6% to 24% chance to spread a random mutation from that fruit to another fruit in the garden.
Other pets cannot mimic or refresh the Rainbow Hydra's abilities. It has a hunger stat of 333,333, one of the highest in the game. It was a tier 47 reward on the Premium Season 2 Pass and is now unobtainable, which makes it a rare pet to own.
