Imaginary Friend?

Whoah! Blake is pretending to have an imaginary friend. He keeps saying, "come on Winnie!" and holding out his hand and pretending to hold her hand. I am assuming he's talking about Linny from Wonder Pets, his favorite show. Ming-Ming has trouble with her Rs and calls Linny, "Winnnie". I just asked him where Winnie is, and he said, "Right here!" and pointed to the air next to him. This tickles me immensely.
