I bought my DS and DD each a pair of Disney Crocs with some jibbitz for them. They both told me that the jibbitz kept falling out. Luckily, we haven't lost any yet. So I went out and bought some round, rubber washers at the hardware store. Perfect solution !! Stick the jibbitz thru the holes in the crocs, and then thru the washer, and they are nice and tight. Good luck !!
