Grow a Garden: How to Get the Hermit Crab From the Coastal Egg

The Hermit Crab is a Mythical pet in Grow a Garden tied to the Summer Harvest 2026 event. It comes exclusively from the Coastal Egg, so it can only be added to your garden while that event stays live. Its passive touches three different systems at once, which makes it useful for players who farm crops, keep other pets, and restock at shops.

Quick answer: Hatch a Coastal Egg. The Hermit Crab drops with a 9.5% chance, and you can only get Coastal Eggs while the Summer Harvest event is running.

How to get the Hermit Crab in Grow a Garden

The Hermit Crab hatches only from the Coastal Egg, and there is no other way to obtain it. To reach the egg, you first need to earn or buy one during the event.

Collect Coastal Eggs while the Summer Harvest event is active. You can earn them through the High Tide Harvest event rewards or the High Tide Team rewards.

If you want a faster route, buy Premium Coastal Eggs from the in-game shop with Robux. These also carry a chance to hatch the rarer Tidal variants of the Coastal Egg pets.

Place and hatch the Coastal Egg. Each egg has a 9.5% chance to produce the Hermit Crab, so multiple eggs may be needed before one appears.

Note: The Coastal Egg is a limited-time item. Once the Summer Harvest event ends, the egg leaves circulation and the Hermit Crab becomes unobtainable.

What the Hermit Crab’s Hermit Pinch passive does

The Hermit Crab’s passive is called Hermit Pinch. When it triggers, the pet pinches one of three random targets in your garden, and the effect depends on what it pinches.

Pinching another pet grants that pet a Medium Passive Boost.
Pinching a plant instantly advances its growth progress.
Pinching a shop NPC restocks a random item in that shop.

Because the target is chosen at random, the Hermit Crab spreads its value across farming, pet support, and shop restocks rather than focusing on one job. That balance works best if you regularly visit the Seed Shop and also want quicker crop growth alongside boosts for your other pets.

Is the Hermit Crab still obtainable?

Yes, but only while the Summer Harvest 2026 event runs. The Hermit Crab is locked to the Coastal Egg, and that egg is available for the duration of the event. If you want the pet, hatch Coastal Eggs before the event closes, since there is currently no confirmed way to obtain it afterward.
