Petit Planet: How to Catch a Langoustine Lobster

The Langoustine is a lobster that lurks in the shallow coastal waters of Petit Planet, and it is more trouble than most creatures you’ll wade into. Walk straight at it and it either knocks you flat into the water or scuttles off. Time your approach correctly, though, and it’s worth a tidy 60 dough each.

Quick answer: Wait for the Langoustine to spin so it faces away from you, sprint in from directly behind it, and hit the grab prompt before it rotates back to spot you.

Why the Langoustine is worth the effort

The Langoustine behaves defensively. The moment it spots you closing in, it reacts, and there are only two outcomes: it either shoves you down into the shallows or bolts before you can grab it. That’s what makes it feel like a small boss compared to the fish and bugs you scoop up elsewhere.

The payoff is the sell value. Each Langoustine you land is worth 60 dough, so a clean run through the shallows adds up quickly once you learn the rhythm.

How to catch a Langoustine

Head into the shallow coastal water and locate a Langoustine. It moves in a slow, predictable pattern along the seabed.

Stand back and watch it rotate. The Langoustine turns on the spot, so track its spin and wait until it has turned its back to your character. This is the only safe window.

As soon as it faces away, sprint straight up behind it. Speed matters here. You need to reach it before it finishes spinning back around to face you, because that’s the point where it detects you and either attacks or flees.

When you’re in range, the grab prompt appears over the Langoustine. Press it immediately to snap it up with your tongs. Hesitate and the lobster will slip away.

Approach from directly behind, not from the side. A side angle still puts you in its line of sight as it turns, which triggers the knockdown.

How to know it worked

A successful grab plays a short catch animation, and a close-up of the Langoustine appears on your collection card. Once that shows up, the lobster is yours and can be sold for its 60 dough value. If you get knocked into the water or the creature darts off instead, the timing was off. Back away, wait for it to reset into its rotation pattern, and line up the next attempt from behind.
