Performing the 'Under the Sea' skill in Forza Horizon 6 is a requirement for certain in-game challenges and is tied to a single, specific location. This area, a small seaweed farm, is situated at the edge of the game's map and is easily overlooked.

Locating the Seabed Road

The designated area for the 'Under the Sea' skill is known as Seabed Road. It is located in southern Ito, west of the bridge leading to Legend Island. While accessible after completing the game's initial tutorials, it is marked on the map by a T-shaped dotted line extending into the ocean.

Performing the Skill

To execute the 'Under the Sea' skill, players must drive through and smash the poles that support the seaweed nets at the farm. It is crucial to verify if the challenge specifies a particular vehicle, as destruction in an incorrect car may not register.

Completing the 'Manta Ray' Challenge

For instance, the 'Manta Ray' challenge requires players to earn four 'Under the Sea' skills while driving a 1984 Opel Manta 400. This vehicle can be purchased from the Autoshow for 152,000 credits, or acquired for free by completing the third tier of Dirt Trials within the game's journal.
