Sometimes its hard to tell who is who or what they are. John was really good about keeping his monkey costume on. I think he felt comfortable in his own skin. :)
Brooke was a white kitty with a tail (which is really cute). I think she should have had little horns on her instead of ears.
Matthew is Blue from Blues Clues. He is so adorable, just like Blue.
Jacob wanted to be Santa Claus. Maybe he'll turn out to be a very generous and giving child.
