Something I really like about the
Masha and the Bear animated series is that several of the characters are shown reading quite often. Especially Bear and
Rosie the Pig. In the second season episode
The Puzzling Case, Rosie was sitting on the stairs reading
The Adventures of Sherlock Holmes by Arthur Conan Doyle. Rosie was enjoying the story until she was surprised by
Masha who started reading the book with her.
The two would later find themselves trying to solve what they thought was a mystery. Well, it was sort of. They went over to Bear's house and it was a mess, and the food in his refrigerator was missing and so was Bear. Although, Masha and Rosie successfully figured out what happened to the missing food, they ended up ruining Bear's attempt at relaxing. Earlier in the story, Bear was working on a new puzzle but he realized that once Masha showed up she would somehow ruin everything. So he decided to build a little loft in a tree so he could relax, drink his tea and work on his puzzle. Which ultimately led to Rosie and Masha solving the mystery of the missing Bear, even if he wasn't really missing.
