Tip: You can use Lunar Magic's Overworld Layer 3 Editing system to edit or create your own layer 3 images (castle bricks, fish, rocks) and apply unique effects per level via the Layer 3 Bypass in the main editor.
Previously part of Davros' Fishin' Boo pack, now submitted separately for ease of search and to fit current standards. Removed unnecessary code from the Fishin' Boo Boss, the white flame and the light sparkle, and also took off the secret exit trigger from the boss as it didn't work at all. Now, the extra bit defines if it'll trigger the level end or spawn a door, as opposed to using Extra Property Byte 2. Converted the white flame block to GPS (db $37). Included JSON files for new PIXI (CFG files are still provided for old PIXI users). Added screenshots, tags and SA-1 support.
