We got the code, now we need the potato. This doesn't need to be fancy. In fact, you can make one with not much more than a rubber band.
Just so happens that this guide is being written near Easter time. This provides us the opportunity to make our potato out of a currently readily available item...
PLASTIC EASTER EGGS!
I just went to the store and looked around. I ended up finding several styles of plastic Easter eggs that were big enough for the Circuit Playground to fit in. Some of these had candy in them, so I had to eat that first. The one with the clear top had a toy inside. Others were just empty.
This egg style could fit the 3 x AAA battery pack, as well as the small LiPo battery. As a bonus, it had a clear top! :)
Here's the first egg with the Circuit Playground and the small LiPo battery installed. Ready to be closed up!
Here's the second egg with the Circuit Playground and the 3 x AAA battery pack installed. Good to go!
Since the HPE (Hot Potato Egg) is going to be tossed around a lot during game play, it is a good idea to add some cushioning to the inside. You can use anything soft and stuffable, like bubble wrap.
Reuse some bubble wrap from a previous shipment. Some of the Adafruit shipping envelopes are even made of bubble wrap.
