Spornbob: Deep in Bikini Bottom is an adult parody visual novel made with Ren'Py by FRANKTOPIA. You play Frank, a fugitive who flees prison by sea, survives a storm, and washes up in Bikini Bottom. Stranded, he takes on SpongeBob's identity and tries to live that life while uncovering strange encounters and risqué secrets. The game uses 2D computer-generated art, animated scenes, and a sandbox-style adventure structure.
The current build is v0.0.14 Public, released August 14, 2026, and development remains ongoing. It runs on Windows, Linux, and Mac, with English text and no censorship. This update expands content tied to Sandy and Mrs. Puffy, adds a new night worker named Abby, and introduces a boat piloting test minigame, a new minigame with Sandy, a new boating school area, fresh Treedome action scenes, extra dialogue, music, and about sixty general improvements. The developers suggest starting a new game.
