Easter egg

Easter egg are usually hidden surprises or tricks. They are small surprises programmers add to their media for players to uncover, much like chocolate eggs in a real-life Easter egg hunt. Many Easter eggs are purely for entertainment. Some examples include hidden names or faces of programmers, references to other games, or messages for the player.

Easter eggs should not be confused with glitches, cheats, or techniques. Many do not alter gameplay at all, and are added on purpose.

Characters

 * 's down special move, Stone, has slim chances of turning him into a miniature Landmaster or the Moon from The Legend of Zelda: Majora's Mask.
 * Normally, when performs his down taunt, a brief melody of the FINAL FANTASY theme plays. If he is under the effect of a Metal Box, however, a metal remix of the FINAL FANTASY fanfare plays instead.

Stages

 * In Central Highway lies a hidden dilapidated sign depicting the Robot Master, Cut Man in his classic 8-bit form, found beneath the middle platform. It cannot be seen in regular gameplay, or by zooming all the way out the stage's camera as the regular movement pattern restricts panning far below the middle platform to fully see the sign. In order to see it, it requires the player to trick the camera by letting a character stand on one of the two platforms from the sides as they are collapsing. Right when the character is about to disappear on-screen, the player has to pause the game, which will bring the camera's angle out beyond the low boundary, thereby allowing to finally see Cut Man's sign. This Easter egg was especially prepared by developer Steven Borgers.
 * Waiting Room will change its scheme to fit a particular holiday according to the computer's internal clock. For example, selecting the Waiting Room during the month of October will give it a Halloween motif.
