you find lost cave on leaf green on 5 island. after resort gorgeous.
Just keep running around and you will eventually find one. It does take a while for Pokemon to appear in the lost cave. Murkrow is RARE in the lost cave so you won't find it easily. It can only be caught in the Firered lost cave and Misdreavus can only be caught in the Leafgreen Lost cave. You cannot get Misdreavus anywhere in Firered. It is absolutely exclusive to Leafgreen.
