Ok, my grandfather brought me so many educational videos and I just thought of one I used to watch religiously. It was a dog that was a detective, always wore a coat. They would go over math and reading. If I remember correctly, there's a scene where he travels in a pyramid and with the help of a ghost, they go over spelling and reading. There's also a female rabbit or sheep and there's a lot of songs in the video! Please if anyone knows what the name of this is TELL ME! Thanks.
