Yeah, Adam, Ariel, and Tiana are happy at the end of the movie or right before the ending. like Tiana was happy at the end. Ariel was happy about the end too. So It makes me happy with happy tears.

Arrrrrrr. :)

She was like "OMGZWOW! MY LIFE'S DREAM IS LIKE COMPLETE AND I HAVE A HOT GUY AND I HAVE LEGS AND MY FATHER APPROVES AND I'M GETTING MARRIED AND I'M GOING TO BE A QUEEN AND OMGOMGOMG!"
Beast was just sort of like "omnomnomWOMAN"
Enchanted objects weren't very bothered at all. Though, I expect Lumiere and Babette were happy.
Tiana was more shocked than happy. Same for Naveen. They'd come to terms with the fact that they'd be frogs forever.

Well, of course Ariel wanted to become human very much (although it was not again,
but I pick the Beast. If he didn't become human again, his life would be almost meaningless. He was alone, there were no friends etc.
Enchanted Object(s) have each other, Tiana and Naveen could live happily ever after even being frogs, and even Ariel theoretically could meet some merman and be rather happy.

^OMFGGG
Straggy you are hilarious xD

Definitely Ariel. That really big smile she made is enough explanation for me.

I was also way happy to see Tiana and Naveen become human xD that was epic cuteness!

I'd have to go with Ariel...the look on her face is just priceless when she gets her legs back!

and Ariel, obviously

Yes, Ariel needed to be human to be part of Eric's world, but the Beast (a.k.a the Prince) was the one who was really in need to become a human. If he stayed a beast, he'd stay a bit lonely, even if Belle was with him. After all, they got married. And Ariel could also be with Eric as a mermaid (she could just jump out of the water to be with him).
