Okay, it's a toy. But if the pump is on it, you should also be able to pump? Or did I miss something ?? We have now already the second pump: The first pump was the matching hangers there and was no longer usable after a short time because the moronic construction became leaky se. Say: If you pumped it squeezed the water out everywhere just barely out of the syringe. A huge disappointment for all. So I've tried to seal. The pump functioned as such a little longer than the original manufacturer. Eventually, of course, wars and so over. Since my son absolutely wanted to use again with the pump I have a new trailer donated him this year. That thing was not even properly out of the box and then it was no longer. The construction was still leaking and shaky. So I got the columns with adhesive filled and sealed so. With the result that now difficult to pump goes once the cylinder full of water. But hey, that's Muckis :-) and the pump pumps.
An for the whole thing is a great idea and very well received by the kiddies to. So the greater the disappointment because that goes so quickly broken.
