⚡ What its two abilities do
Three-Headed: every 41 minutes 40 seconds at base weight, the Hydra gains a level, instantly hatches one of your eggs and gives a fruit Terran (×75). The catch, per the wiki: all three must be possible. With no egg in your garden, or the Hydra at level 100, or every plant already Terran, none of them happen.
Earth Diety (the game's spelling): selling a Terran fruit has a 6% chance to put one of its random mutations on a fruit in your garden. The Frost Dragon and Cerberus have the same kind of sale ability.
Its 333,333 hunger is the second highest in the game, behind the Wendigo.
📈 Hydra stats by weight
| Pet weight | Cooldown |
|---|---|
| 10 kg | 40:00 |
| 60 kg | 31:40 |
| 100 kg | 25:00 |
| 320 kg | 20:50 |
| Pet weight | Spread chance on sale |
|---|---|
| 10 kg | 7% |
| 60 kg | 12% |
| 100 kg | 12% |
| 320 kg | 12% |
The sale-spread chance doubles to 12% at 60 kg. Three-Headed's cooldown falls only 10 seconds per kilogram (25 minutes at 100 kg), and its 20 minute 50 second floor needs about 320 kg.
🐉 Keeping it working
Always have at least one egg incubating and some fruit without Terran, or Three-Headed stops completely.

❓ FAQ
What does the Hydra do in Grow a Garden?
Every 41:40 at base weight, it levels itself up, hatches one of your eggs and applies Terran (×75), but only if all three are possible. Selling Terran fruit has a 6% to 12% chance to spread one of its mutations.
Why isn't my Hydra doing anything?
Three-Headed needs an egg to hatch, room to level up, and a fruit without Terran. If any is missing, none of the three happen.
