What you do is either get them in emerald and trade [easy way] or waste about 50 minutes looking in that beaver dammed cave
Only zubats =)
you use a ultra ball
No, there are not any rare Pokémon located in Altering Cave. Some of the Pokémon that can be found in this location include Mareep, Pineco, and Shuckle.
Altering cave is on 5 or 6 island.
There are no moveable rocks in Altering Cave.
Altering cave does not change into traveler's cave. Altering cave can only offer new Pokemon (since all it offers are zubat) after using Mystery Gift.
you'll never find any other Pokemon in the altering cave sadly
It's normally no pokémons in the altering cave i heard that you must do something ;)
Only zubat can be found in Altering Cave. Altering Cave was a location intended to be used for an event where Mystery Gifts could change the pokemon encountered in the cave, but these Mystery Gifts were never officially distributed.
In Altering Cave all you find are Zubats. The only way to get rare Pokemon from it is to use mystery gift but I think the event has passed so at this point it is pretty useless.
as i recall you can only find zubat in altering cave but after you do some certain event then you can find other Pokemon like teddiursa
You can catch Mew two (the person who wrote this is lying you have to go to currulean cave to catch mewtwo srry for getting your hopes up)
