Daniel and Prince Wednesday are making a lemonade stand together. But when they don't agree about how to hand out the lemonade, they need to learn to express their mad feelings so they can find a solution - and provide lemonade for their neighbors! Daniel is at the beach with Miss Elaina and they're building a sandcastle. Suddenly, the creation they worked so hard to make gets knocked down by a wave, and that makes them mad, mad, MAD\! Dad teaches the kids that it helps to express your mad feelings.
