>Rock/Ghost Fossil
A fossilized egg that rolled out of its nest and,never hatched. Has the color and appearance of the old Gen 2 style egg. It would have high defenses, but not much offense to use anything other than status moves.
When it drops to half health, the egg cracks, a pair of glowing red eyes shine through, and a ghostly image of a dinosaur appears around it. Could be a randomly determined first stage fossil, or could be something based on the substitute doll. Either way, that boosts its speed and offenses afterwards.
