I would write this:
Dear, Children and Parents, Club penguin is the best site to donate money.
You don't have to thanks us, you deserve this much money than we do.
If we were you, we would be thankful to the world and especially club penguin and penguins from all over club penguin.
I hope every penguin in club penguin donated some money.
My best present on Christmas to give you guys money.
That is all I can say.
