Pooh's Double Trouble My Friends Tigger & Pooh : Season 1 Episode 37

Porcupine is helping her friend Turtle to move into the old cave and they have many heavy deliveries to make. One of the items they're transporting is a huge mirror. As they go about their business, Pooh is playing with Piglet and spots what appears to be... himself. He calls in the help of the other Super Sleuths and soon everyone is seeing duplicates. Everyone is very confused as they split up and can no longer tell if they're running into themselves, their friends, or one of the many duplicates.
