That is not us but we had one as well with a Patrick shirt on. We got it off Amazon and you just blow it up with your mouth like a normal inflatable. Let me see if I can find it.

Unfortunately not in stock right now but here it is on Amazon. I'm sure you can find it somewhere else as well. https://www.amazon.com/BigMouth-Inc-Wacky-Waving-Tubeman/dp/B01N4PZ9EG/ref=sr_1_30?srs=3018977011&ie=UTF8&qid=1508426593&sr=8-30&keywords=pool
