If you attended a Nintendo of America event, multiple pokemon appear in Altering cave as well as the means to change Deoxy's form.
There is no Entora cave in PokÃ©mon Emerald. There are many caves in PokÃ©mon Emerald such as the Altering Cave.
nothing cool about it really...
You can only find Altering cave in Fire Red, Leaf Green and Emerald. Its not available in Sapphire or Ruby.
Nothing just leave.
Altering Cave apears on route 103 after you beat the Elite four.
Beat the elite four the cave should open.
Altering CaveIn Emerald, FireRed, and LeafGreen, Altering Cave appear useless for only having Zubat. If you go to a Nintendo Event with a Wireless Adapter attached, you'll get to catch rare Johto Pokemon.
its pointless unless you like zubat
I've heard it has something to do with the Altering Cave.
