A Pokemon Egglocke is a Pokemon save that has PC boxes full of eggs. These Pokemon games are played with a specific set of rules: 1. Any Pokemon you catch must be swapped for an egg that is in the PC. 2. You can only catch the first Pokemon you encounter in any area throughout the game. 3. When a Pokemon faints it is classed as a death, and the Pokemon has to then be released or put in a PC box exclusively for 'dead' Pokemon.
