Eva is here.

One day, they looked around and there she was, Eva.
Eva was a cute and nice Oval, and she looked beautiful.
Bob and Willy had never seen an oval before, so they liked her a lot.
And just like them, Eva could spin, rotate, twirl, and gyrate!
Eva became their friend, and the three of them played together all day long.

It was a perfect universe, a perfect world!
They were incredibly happy together.
Until one day...

What do you think is going to happen next?
Why do you think Eva is shaped like an oval?
What is the difference between an oval and a cube?
Why do you think they can't go somewhere else?
