Help us solve this mystery

These hats arrived in the post the day before yesterday. We have no idea who sent them to us. They were mailed from a place called Hooplah Interactive Inc. in Toronto so we thought it might have been a gift from Phil and Luis in Grimbsy. Then again, they could have been sent from our friends Donna and Julie.

I think whoever sent the hats did so because they know how much we like to soak in our hot tub but won't go tubbing in the rain. Perhaps they thought these hats would allow us to enjoy the tub in any weather. Just look at the expression on my face. Can't you see how touched I am to have such thoughtful friends?

Please help us solve this mystery. It's ok if it's you who sent this gift to us - we still love ya.
