The Legendary Starfy

The first (and only) localized Stafy game.

Unused Backgrounds
Some of the stage backgrounds are leftover from Densetsu no Stafy 4, such as Lobber's Cottage and Pulling Ahead Lake. They can be found in invalid rooms.

Costumes
Graphics for unused costumes for Starfy and Starly (aka Stapy) can be found:
 * Mermaid Suit: It has swift swimming moves. Oddly enough, graphics for hiding in a shell as well as big heart graphics can be found: these are normally animations for the save mermaid.
 * Frog Suit: Has animations for extending his tongue, and spinning.
 * Cockroach Suit (Starfy only): Has flying animation (with Stafy visibly tired), sleeping animations, and one for whipping enemies.

Other
A tall yellow creature.
