CuBees

The CuBees are a collection of six little square, plastic farmyard critters - the kind of square, plastic farmyard critters that like to hang out together and sing. And when they sing - their square, plastic, farmyard faces flap back and forth in time to the music.
Behind their square plastic faces they have square, plastic tummies and in their square plastic tummies they keep their square plastic offspring. These square plastic offspring live together like little Russian dolls and look just like their parents - the only real difference is that they're even more useless. They don't even sing!

But they do silence like you've never heard before.
You can stand the parent CuBees in a line and have each one perform a solo or stack them and they'll treat you to a duet - they've got little electronic connector points so that when they're stacked they can treat you to a full farmyard chorus
