How about Fozzie?

[This earned a negative and a headshake from the bear. He'd look terrible in a hat.]

What about Basil? Or maybe Jasper!

[The Grizzly Cub looked thoughtful... then shook his head again. Lucas dropped on his rear and pressed his hands against his head in an adorable look of childish frustration before suddenly looking absolutely inspired.]

I got it! How about Sir Bearington?

[Both the bear cub and boy stood, looking absolutely excited about the name before they both thought about it a while.]

Naaaah...

Doesn't sound like he can talk... but Lucas understands him just fine.

... I think I got an idea. Does Walter sound good? Its the name of a writer who wrote a story about a bear so...

[There was a pause. Then the Cub voiced his approval, earning a cheerful whoop from Lucas.]
