What is the mood of the park scene in the following passage?

"There were lots of other delightful things in the park. There were ponds with gold and blue and green fish in them, and trees with beautiful parrots that said clever things at a moment's notice, and humming birds that hummed all the popular tunes of the day. Bertha walked up and down and enjoyed herself immensely, and thought to herself: "If I were not so extraordinarily good I should not have been allowed to come into this beautiful park and enjoy all that there is to be seen in it,' and her three medals clinked against one another as she walked and helped to remind her how very good she really was."
