I suppose in a few days you'll wish you had a picture, just as much as I wish you did! (Once the ARRRGGGHHH stage is over).
I hope you're able to get the rest of the stains out - maybe Clover was just telling you she wanted pretty painted toenails for the holidays?
I definitely know that "Don't know what happened here, Mommy" look too...it always seems like Diesel is saying "it was her, Mommy, I'm a good boy", and Indy is saying "are you kidding? I'm too little to do anything so naughty"
Next time they'll probably try to blame accidental poops and things on me!
