Destructoid has released guidance for obtaining the 'Bean' achievement in How to Fish, described as one of the game's most demanding accomplishments. Whilst a standard playthrough takes five to six hours and allows players to explore multiple islands and activities, this achievement demands completing the entire game and defeating the final boss—a whale—in under an hour, necessitating constant optimisation and skipping optional content.

The published strategy directs players through two key locations with specific acquisition sequences. At the Lighthouse, the approach involves obtaining Brass Knuckles and necessary upgrades before defeating the Spider Crab boss to secure boat keys. Players then proceed to the Volcano, where they systematically accumulate fishing equipment, weapons like shotguns and assault rifles, ammunition upgrades, and various lures using precise resource allocation. The guide emphasises maintaining a supply of healing items and studying boss attack patterns to successfully navigate encounters, particularly against the whale boss, within the one-hour constraint.
