The glitch Egg is Egg data with the Pokémon specified to hatch from it as another Egg, and thus acts as a glitch Pokémon.

Egg data in Pokémon games usually have their own entry in the same chunk as other species' data. In Generation II, number 253 stored most of the data associated with the unhatched Egg. For any Pokémon in a Trainer's party, there are two values stored per Pokémon that indicate its species. The first value, found in the Pokémon data structure, decides how the stats grow and what sprite appears in battle. The second value is typically exactly the same as the actual species value while it is in the party that almost only decides what sprite appears in the party screen next to the Pokémon's name. However, when the Pokémon is still an unhatched Egg, this second value will be 253, signaling the game to treat it as an Egg. Unstable hybrid Pokémon are Pokémon with these two values set to different species.

It has a footprint with the number 253 embedded in it.

Glitches caused

Hatching

Hatching

This glitch Pokémon is an Egg that will hatch into an Egg. Therefore, the Egg sprite will appear next to the glitch Egg like a normal Egg and the glitch Egg is forced to hatch into another glitch Egg every 30,720 steps.

Egg-Pokémon duplicity

This Pokémon both acts as an Egg and a Pokémon, depending on the circumstances. The player can deposit all Pokémon but glitch Eggs into the PC. Also, it is possible to give away the player's last Pokémon other than a glitch Egg by giving a Pokémon the Mail from Randy and delivering it to the man on Route 31.

In battle

The glitch Egg in battle

If the glitch Egg is the only Pokémon in the party, interesting things happen when it is used in battle.

In Pokémon Gold and Silver, if the player enters a battle, the game will instantly reset.

In Pokémon Crystal, it can battle but has no moves, so it will always use Struggle when told to attack. If it faints and the player whites out, it will not be healed. As long as the player has no conscious Pokémon in their party, all battles will be over right before the player sends out a Pokémon. The game behaves as if the player had won, but no experience is gained.
