Happy St. Patrick's Day!
Elaine, I have several of the same ones that you have, but my collection is much smaller. They all live in my car, and I change them at least once a month, this month will get 2 changes, after today I will take off the St. Pats day one and put on the Easter one for a couple of weeks. For New Years, I use the one with the gold ears, it is the closest I can come to that.
We have not even thought about fish extender gifts yet. We will get to that later.
Ours live in our car too! We change them out frequently, and even put one on my folk's van too, but they get rather dirty and don't clean up very well

There are so many cars in NJ with Disney toppers! We love seeing the different ones.
