I've always liked the dreamy style of your animations, but I just don't understand the meaning of chocolates or the frogs in this one. I like the messages that you send; then again, there are two messages here: treating a princess and having one, of all, nearby at all times. If I was you I'd focus on one of the two.
But yeah, besides that, the frogs aren't doing much in the video, and we never find out what's behind the doors. Since this is a singular episode (being a holiday edition), I don't understand why you'd put mystery there. It's not like you'll make a sequel.
