The video shows a cartoon pig standing in a classroom with a purple floor and green walls. The pig is wearing a black dress and has a happy expression on her face. In the background, there are colorful blocks with letters on them and a green chair. The pig is holding a whiteboard with a letter "Y" on it. Two other characters, a rabbit and a dog, are also present in the classroom, each holding a whiteboard with a letter "X" on it. The pig is talking to the characters, and they all seem to be in a cheerful mood.
