This book is about Charlie, a curious little American girl who received a piggy bank on her birthday months ago. She knocked her piggy bank down and had a flashback of all the ice cream she ate on her birthday. Now Charlie wanted some ice cream. She showed her dad that it was still empty. He explained that whatever she found before the truck arrived, he would double it for her. Charlie was now on a mission to put some funds in the piggy bank. Charlie searched high and low for coins. She made it just in time, and her dad kept his word.
