Unused extremely small seal-like character found in development files for Yoshi's Island. While characters fitting into a standard 16x16 pixel square are common for other SNES games, Yoshi's Island characters are usually larger, with even Shy Guys being 16x19 pixels.

Level 5-4 of Yoshi's Island, Sluggy the Unshaven's Fort, contains a lengthy section that is supposed to be "autoscroll-like" as it contains no floor and Yoshi is intended to use a Support Ghost, a moving platform with a specific pattern of moving and stopping, to get across.
However, Yoshi's maneuverability in this game is actually high enough that by using frame-perfect Flutter Jumps and bouncing off some of the flying enemies, it is possible to cross the entire section without using the Support Ghost and skip having to wait for its movement.
