One of the best $10.00 I've ever spent!
I was going to put play sand in the box, but then I saw the idea for "natural looking" aquarium rocks on Pinterest and used them instead. The box we already had along with the handy-dandy wooden tray that we use for all kinds of things.
The kids LOVE this toy! It's so popular, that I use it as a good behavior reward. Towards the end of the day, if a child has been good, he/she gets 15-20 minutes with the diggers! Woo-Hoo!
That's all for today! Hope you all have a fun day! God Bless!
