Sea Trap is an item from Don't Starve: Shipwrecked DLC. It's a Nautical item used to catch Wobsters, but will not catch Bottlenosed Ballphins, Jellyfishes, or Dogfishes. It can be crafted at a Science Machine with 4 Palm Leaves, 2 Empty Bottles, and 1 Jellyfish. It is also a reward from the Yaarctopus in exchange for Jelly-O Pop.
Once set, Sea Traps can be baited with food, which are attractive to Wobsters. Baited or not, a Sea Trap will trigger once a Wobster moves close enough to it.
Sea Traps are set by placing them in shallow oceans and can be picked up again at any time. They will move a bit of distance before settling completely when deployed. To bait a Sea Trap once set, simply place food in it. Bait will be consumed upon a successful catch, but will be given back if the player picks up the Sea Trap with the bait still in it. Once a Sea Trap has caught something, it will drop its hook with a cage, with the Wobster in the cage.
Sea Traps do not need bait in order to catch Wobsters; if a Wobster touches the Sea Trap for any reason, it will possibly catch it. This means if a Sea Trap is placed directly on top of a Wobster Den, it will catch the Wobster when it leaves home or comes back.
When a Sea Trap is picked up from the ocean and is still set to catch a Wobster, no durability is lost, allowing it to be moved around freely. When a Sea Trap is picked up after catching a Wobster (or failing), it will lose durability.
Sea Traps can also be used to mark notable areas on the map, as Trap icons appear wherever they are left.
- Limpets are seen in the Sea Trap's art, hinting towards the ability to bait them with it, among most other food items.
- Wilson's examination could possibly be a reference to the show Deadliest Catch.
