I wish I keep my child dino collection....they all had gotten leaks then tossed .

Awwww I'm so sorry to here that my draconic friend *draggy hugs*. Mine was leaky for many years but he was largely stored away and forgotten (unfortunately the other one did get thrown away at some point sadly). I remembered him one day in college when I began actually enjoying inflates and lo and behold he was still there. I took him to college and rode him quite a bit. Thank goodness I'm a featherweight. He's had virtually every negative seam repaired since I've had him but I still love him a lot. Hopefully you can find more one day. I don't think that they're too terribly uncommon but I'm not really sure.

I come from a family that everything is trash at the end.

I know the feelings
