The Goblin Miner is a Mythical pet you can get from the Smithing Event, but the actual hatch chance is extremely low—only 0.54% when digging on the event island. Because of that, many players treat it as a collection pet or a flex item, while others get it simply because it has one very simple but helpful passive ability.
The Goblin Miner is designed like a small, chunky voxel-style goblin dressed as a miner.

Here's a breakdown of how it looks:
Overall, it looks like a tiny goblin who's been working in the mines for hours but still somehow has energy left. Very fitting for a pet focused on digging.
This is the “true” way to obtain the pet.
This makes it extremely rare. Even with good luck, most players won't see it unless they dig a lot.
If you don't want to gamble with RNG, you can buy Goblin Miner Pet from U4GM.
Every 5 minutes, the pet has a 2% chance to give you a free dig.
It's not a crazy strong passive, but it does give you a slow drip of progress over time. Think of it as bonus rolls you didn't have to work for.
This is fairly standard for mythical pets—not too high, not too low. Easy to maintain.
Let's look at why players care about the Goblin Miner:
Mythical pets always hold some value in trading because they take either luck or money to obtain.
The 0.54% chance makes it much rarer than common event pets.
Even within the mythical tier, this is on the lower end of drop rates.
Since you can buy it for $9.99 at U4GM, this gives us a reference point.
What this means for in-game value:
Overall, its value is shaped mostly by rarity and collection demand, not raw power.
The passive is okay. It's not game-changing, but it does add free progress over time.
Collectors usually value it more than efficiency players.
Here's the honest breakdown:
The Goblin Miner isn't a must-have, but it is a cool, unique pick.
Yes, but in a slow-and-steady way.
Its passive won't carry your gameplay, but it's a nice bonus on top of your regular digging. You won't feel a big difference immediately, but over many hours of play, those free extra digs can add up.
If you want the strongest gameplay pet, this isn't it.
If you want a fun, rare pet that still helps a bit, the Goblin Miner is a solid choice.
The Goblin Miner is a mythical, rare, and event-based pet with a 0.54% hatch chance from the Smithing Event. It has a cute but rugged goblin-miner appearance and offers a simple passive ability that occasionally gives you free digs. While it won't change your entire game, it's a nice collectible with some practical benefits. Its value is mainly driven by rarity, not raw power, and buying it for $9.99 is mostly for players who want it without grinding the event.
