I had to figure it out myself. I read other reviews and knew it was true. See attached photos. There is a secondary fill port that is separate from the flush port. It's wider and needs to be squeezed to open the hole. Ideally you should fill it with water before blowing it up with air, but I found the hole after blowing the game. He needs a lot of water before he becomes independent. If you don't have enough water, the product has a slight tilt as shown in my photo (but it works quite well in this case too!). People are disappointed with this product. My nephew loved playing with it and when it included a water base he loved just knocking it over even more! Overall a good product but needs better instructions!
