Happy birthday Woodsy!!
I haven't just sent you a Sooty video for your birthday,
I spotted something while watching this with my daughter recently, an inflatable Stingray submarine!!
Wrong colors, so maybe a knock-off???
I've included a fuzzy picture too but if you watch the video it's on in the 1st few minutes of the episode!! https://youtu.be/WFrZCPqqXKk
