Although the Clumsy Nun is sad, is good to see the rest of the nuns are doing their best to cheer her up.
And I'm also glad the ducks doesn't have any hard feelings with her, despite she tried to give their house to the dog.

Poor Clumsy.... Good that the Ducks are always there for her, regardless of situation.

Animal Masks? A reference to a Murder Mystery Manga once again and who is wearing the Frog Mask if not Froggy? Probably Sheep Nun.
