While I cannot tell you how many actual Jolly Balls we own (not because I can't count that high on all 4 paws - but mainly because there's this show about hoarding... and we fit the bill) this is our favorite - somehow that baby jolly got in the big jolly and we try like mad to get it out - so far our efforts have been thwarted by fat heads and too much slobber - but we're still making a daily effort to free the little jolly - will keep you posted as things progress - but as it stands this is on more of a 5 year plan - so be patient.
