From the sprout tower at night.
Nope, Ghastly will only appear during the evening/nighttime.
The first place you can find Ghastly is in the Sprout Tower located in Violet City.
I have herd ghastly is in the sprout tower
Ghastly will evolve at level 20.
Ghastly can be found in Sprout Tower in Violet City.
Time capsule... Pokemon / moves from Gold / Silver / Crystal and newer do not transfer back though. So the answer is yes. It is a long time before the capsule is available though just as a fair warning. You can transfer all Pokemon TO G/S/C and newer, and if it existed then you can trade it back (Pokemon like Ghastly and Rattata)
the name is ghastly
First, you need to catch a Ghastly, which can be found in the sprout tower or caves at night. Evolve it into a Haunter and then trade it. At that it will evolve into Gengar which you need to have it traded back to you.
You can usually find Pokemon like that in a cave.
