One of the fun things about the Plus is that you can now have Mii's for your pets! The human child and I created Mii's for all the corgis (their coloring, ears, tail, and fur can all be adjusted) and logged their weights. Ziggy weighs the most (no surprise - he's the biggest), Maggie's in the middle, and Denzil weighs the least.
Here's a screen shot of our Mii family:
Now I can chart the pack's weights. Too bad they don't have fitness exercises for corgis. Maybe in the next version.
