Here's one way to recycle them.
Step 1: Collect
We have way more in the house than I can handle so came up with this idea of how to use the ones they're no longer interested in.
My girls now give me toys they're no longer interested in so I can turn them into something new!
If you don't have kids then check your local secondhand stores, & flea markets, as some shops and people give these away.
My girls have these given to them almost every time we go to a flea market, or second hand store, as well as gifts on birthdays, Christmas, etc.
