Easter egg

An Easter egg is a usually hidden surprise or secret trick added by programmers onto to their media for players to uncover, much like a chocolate egg 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.

Below is recompilation of the many Easter eggs found in the McLeodGaming media.

Characters

 * 's down special move, Stone, has slim chances of turning him into the Moon from The Legend of Zelda: Majora's Mask, a miniature Landmaster from Star Fox 64, or a golden statue of Kirby.
 * The yo-yo which appears during 's up smash and down smash has a logo on it that reads "SUPER NINTENDO 2015", with "MOTHER" written underneath it. This may be a reference to the game Mother, which released worldwide under the name EarthBound Beginnings on the Wii U Virtual Console in 2015. However, the game initially released only for the Famicom; its successor, , released for the Super Nintendo Entertainment System before being rereleased on the Wii U Virtual Console in 2014.

For instance, some characters in this form reference other stuff within their series such as  resembling his spherical form from  or  taking its infamous seen-from-above look from the.
 * Normally, when performs his down taunt, a brief melody of the  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 of 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 off-screen, the player has to pause the game, which will bring the camera's angle out beyond the low boundary, thereby allowing the player to finally see Cut Man's sign. This Easter egg was specially prepared by the developer Steven.
 * 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 theme.
 * ＣＬＥＯＤＢＯＴ can be spotted very rarely on the monitors of the Waiting Room during the Halloween motif.
 * In Nintendo 3DS, if a player has their name set to Refurin, Jamal, or ElvisDitto, the stage will automatically be set to the yellow, orange, or red coloration, respectively. This references each of the aforementioned developers' favorite color.
