Mystery Singer 4

We're coming up on our last contestant for this round! Can you guess who this is?

Who is the potato?  Here are some clues:

"I used to work with little ones, but now I'm near the books.

If you see me after school, you know that I can cook.

You'll know me by the socks I wear,

And for my love of bears.

You'll see me walking everywhere,

But please don't stop and stare."

Reveals tomorrow!
