Daniel Tiger and Prince Wednesday are looking forward to playing at the beach, until it starts raining and they get very mad. After Mom Tiger helps the boys deal with their mad feelings and they’re calm, they come up with a grr-ific plan to make a beach--indoors! Later, it’s New Instrument Day at Music Man Stan’s Music Shop. Katerina Kittycat gets mad when someone else picks the instrument she wants to play. Music Man Stan helps guide Katerina through her mad feelings.
