Bear In Underwear (Lost Prime Pilot)

I was looking for a lost piece of media, called Bear In Underwear. I saw it on Amazon Instant Video (Prime Video)

back in December of 2016. I was 8 years old. It seems to be a mystery on where it is now, compared to If You Give A Mouse A Cookie, or A Snowy Day, two Prime kids' shows based off of 2 famous books, published in the 1970's. And there's no way Prime Video would make a series based off of Alexander And The Wind-Up Mouse, published in the late 60's. I have a few images, but there's no way they would be on Fandom.
