From Bulbapedia, the community-driven Pokémon encyclopedia.
The Amorphous Egg Group (Japanese: ふていけい Indeterminate), known in Pokémon Stadium 2 as the Indeterminate Egg Group, is one of the fifteen Egg Groups. As of Generation VI, 49 Pokémon belong to this group.
Most Pokémon in this Egg Group are enigmatic in appearance, and the name reflects this. Its many members are based on a variety of things such as gases, blobs, inanimate objects and soft-bodied organisms. Most are capable of floating off the ground. Many of its members are Ghost-type Pokémon.
The majority of members in this Egg Group are exclusive to it. Very few members are capable of breeding with Pokémon of other groups.
