Gastly from Haunting my Dreams

These are the Gastly. 

They were the Minions of the black Fog. 

The black Fog and many Gastly were returning to the ancient Pokémon Tower 

and they looked like a huge cloud of Gas. 

The black Fog was sleeping on the Shoulder of the Statue of the Woman 

and so were a lot of Gastly. 

Few Gastly were awaken when the Group distracts them. 

Then the Gastly were chasing the Group while one of them was teasing 

the Gastly.
