You can find him on an island called Naval Rock, however you need to have the item Mystery Ticket which could only be obtained through an event that has already passed. The only way to get a Mystery Ticket now is to get one from someone else who happens to have one and is willing to part with it. That will be hard though. Not many people still have a Mystery Ticket and those that do may not want to part with it so easily.
The koi pond was part of the mystery boxes. You had to purchase it with farmville cash to take a chance to open a mystery box. You may not get it as there is I think 6 different items that you have a chance of getting. They change whats in the mystery boxes every month. The month for the pond has passed I believe. Hope this helps.
All main roles are filled to try to get a part as an extra your only chance is probally to get an agent. Sorry I really want to be in it too. :\
He won't but Palkia will.
suurounded sea floor 18 must have a mystery part or secret slab in bag, 60% chance of joining.
Well there is no true mystery part in the name "Mystery Dungeon", but I guess you could say the mystery is what you will encounter in the dungeon.
maybe you can get the secret slab and mystery part in your treasure bag
The part of a mystery in which the solution is revealed is called the denoument.
You don't!!
First you need a mystery part or enigma part. Then go to mystery jungle at BF13. Celebi will be there.

You win the game (post ending). get the secret slab or mystery part (same as time and darkness) go to mystifying forest floor 17 and he might be there if so you have a 14/100 chance of recruiting him
