New characters
We are sad to see Otto, Olive and Oscar leave, but I do understand that they are getting older. Oscar's deeper voice is cracking me up.
My kids seem to like Otis and Olympia a little, but someone tell Oona to SLOW DOWN. We can't understand a word that she says, and I'm pretty sure my 7 year old daughter is going to revolt when her nerdy heartthrob Oscar leaves.
You really can't beat that original cast though....
