The wheel on one of the legs on my sons Zoomer Dino got stuck, probably from running it out doors. I have managed to open the body and detatch the leg, but I cant fin a way to open the leg/wheel without risking the plastic. It’s my sons no 1 toy so I’m gratefull for all help.

I must have fixed it last time, but now it’s stuck again. So this time the question is - how did I do it :)
