I cant find Azurill on it, So I'd say catch a female and a male Marill and breed them at the Pokemon Daycare.
Mew Three does not exist.
in some cave
fishing in the safari zone is the easiest way.
Find it north of Solaceon town or evolve a Happiny
put honey on a tree and wait for 6 to 10 hours. or the easiest way is to catch it in eterna forest

You can't catch fairies as they do not exist.
First catch a Marill. Then get a Sea Incese. Go to the day care center and have Marill breed with anorther pokemon. You'll get an Azurill egg.
use a poke-ball on it
use a master ball

The easiest way to catch a Combee is to slather honey all over a honey tree. Apply seven honeys all at once and the tree will start to shake allowing you to catch Combee.
The same way you would catch a normal Pokemon. The only difference is is that the Pokemon is shiny.
Mew Three does not exist.
With a master ball.
get a yoshi!
