Picture too dark, help

Patrick had his birthday at Chuck e Cheese today, The only picture he took with the mouse/rat is too dark. How can I make it better?
These are the 2 I would like to fix.

Thanks Guys!

I fixed it a little bit, but I can't get the "manage attachments" button to work.:frown

Now it works. :P

Here is the other one.

Thanks Teri, At least you can see Patrick now. Thanks.

It's pretty underexposed, so it's lost a lot of detail and is very grainy. This is the best I can do. I ran it through Neat Image after lightening it to try to help with the grain a bit.

Oops, Teri already replied. :)

Yours are better than mine of course! :D

Thanks guys you rock. The other pictures I took turned out, but these two did not for some reason.
