So are you just looking for a place to grind or help with beating Shade's team itself. If so there should be some trainers in the grand hall who can be rebattled. They give the best experience at the moment.
The reason why this occurs is that a variable for the egg is set when you pick your starter from 0 to 18. However the setting of this variable was only added in Episode 15. Therefore the variable always equals 0 as it hasn't been set yet. 0 is the number that yields an Azurill so anyone who hasn't picked a starter when the variable was around is guaranteed an Azurill.
Americans don't own the world edit: Americans are opposed to spelling words with the letter u. A very large percentage of the world spells colour with a u and favourite with a u. Just because you spell it wrong differently doesn't make spelling it with a u wrong.
Also even if it wasn't a misspelling it wouldn't be grammatical error...
I'm not annoyed or anything- don't worry. It just bugs me when Americans go and accuse correct spellings and pronunciations as being wrong (I'm looking at you z). The rest of the world puts up with Americans spelling things differently...
Yeah, this is a hide and seek event. You have to find the litleo in several places then you'll be able to catch it.
I'm not quite sure of all of the locations but look around a bit and you can catch it.
