check out this cool toy!

Oliver got this from my grandparents for his birthday. They are stacking cups, which I couldn't find a decent set of anywhere. The little head has a bell in it so it jingles. Not only do they stack like this...

but they also click together (with the next size up or down) to make balls.

You can even put them all together into one ball if you put the smallest two together and then keep putting the next biggest one on the opposite side. Sewe the colors layered there?

They stack this way...

and you can stack a smaller one on any larger one because they have little grooves in them to fit together.
This is a very cool toy. Oliver likes to use them as bowls (even though they have holes in the bottom) and slurp out pretend soup. He laughs and laughs!
