Holy cow. I used to have one of those. Unfortunately, the quality of the one I had was atrocious. The figures themselves were little more than balloon rubber if I'm remembering correctly. As such, with the filling, they didn't last very long.
Not that any of that matters. I really have no idea how often they show up though so sorry I can't be any help there. Just thought I'd give my experience if you planned to take them out and display them once you find one. Good luck though.
