You can go to the Pokemon Tower for various reasons. For example, to mourn your fallen Pokemon, to watch everything for simple interest, or to feel the goosebumps running through your body.

And now, having been in the Pokemon tower for several minutes, you feel that the air is getting cold. Suddenly, a scary Pokemon crystallizes right in front of you - Gengar! "Gengar, Gengar!" It laughs creepily, looks like it's in the mood to scare you.
