these two toys are driving me mad.

I love them both.  So cute and colorful and simple and fun.
But seriously, the purple ring and the smallest cube are always missing.  I search frantically through multiple toy baskets and under several pieces of furniture on a daily basis, and yet I usually come up empty-handed.  Something about how obviously missing the missing parts are severely offends my toy-organization sensibilities.
I think Bob knows that it drives me batty when the eye-pleasing sets are incomplete and he's stashing the goods someplace.
Or else it's Ben.
