After Azurill has the nightmare.
Palkia is level 48
Spacial Rift
You have to complete the game, up until finishing the post-game storyline. This will reopen Spacial Rift, where you can encounter Palkia once more at the end. He will join automatically, when you defeat him.
U go to mt.travail to defeat drowzee then go to sleep and Palkia will take u to the sky rift (25f) defeat Palkia and you'll probably get him Well that's true but u have to but u have to beat him 2ce
spacial rift
It doesn't matter what your Mudkip's IQ is, it can evolve at level sixteen, unless it is your starter or partner, in which case you would need to have it at a higher level to defeat Palkia. If it is your starter or partner, you need to recruit Palkia.
You just need to wait a while, eventualy you'll get a bad dream and then you will meet palkia soon after.
You have to beat the game them defeat dakari amd palkia and reggigas and few others so then you get manaphy and manphy comes back then you could evolve
