Ok so first of all I love meloetta its my favorite, and to do that is to first go to cafe sonata in castellia city and go to the musician (meloetta must be in your party) and a cutscene will play and after that she will learn a move called Ancient Song. Now, if you go into battle and use that move, it won't only do damage to the opponent but meloetta will change to her piroette form.(sort of like Samus Iran from Metroid transforming out of her suit, its pretty sweet.)
In order to get Meloetta to change from Aria to Pirouette forms, you must teach it the move Relic Song in Castelia City. It will change to Pirouette form when Relic Song is used in battle and will only last until the battle is over.
It is special not speacil. The answer is.... I suggest change it's forms and have battles. That's what I do with my Arceus in my Pokemon Black. I am not trading you. This is your answer. Thank you.
You unlock a place where Rotom can change its forms.
Go to the Route 9 Mall, and descend to the basement. There are several appliances around the basement, they just so happen to be the appliances that match Rotom's formes. Interact with one to make your Rotom change to that forme.
you touch one of the meteors in veilstone city with deoxys as your party leader
Tornadus, Thundurus and Landorus cannot be caught in this game, you have to trade with the original Black/White versions to obtain them there. Supposing you've managed to do that you can use an item exclusive to the sequels to change them into their alternate forms.

Darmanitan will change to its Zen Mode in the events of its hit points going down to half of its hit points.
You do not go anywhere in "Pearl" to change Rotom's forms because you can't change its forms in "Diamond" or "Pearl." Rotom is only capable of changing forms in Platinum, HeartGold, SoulSilver, Black or White.

I don't think that you can particularly CHANGE your pokeballs in pokemon. It is a really RARE sight for pokeballs to change forms. If it has maybe it is a glitch or something. Otherwise, I think it is impossible for pokeballs to change forms.

petilil, throh, zehkrom, rufflet, braviary, solosis, and their evolve forms.
You go to the meteorites in Veilstone city
