Sam and Julia are on their way home from Rose's doggy school. Julia's been training Rose and shows Elmo a hide-and-seek trick. Elmo wants to play hide-and-seek with Tango too. Sam and Julia help Elmo teach Tango teach the trick with three parts: sit, stay, and find. When Elmo tells Tango to sit, she listens and sits. Elmo starts exclaiming "Tango's sitting! Tango's sitting!" Sam notices Elmo jumping up and down and laughing a lot. Elmo has so much energy and feels excited to teach Tango that he can't focus. Sam and Julia show Elmo how to take a slow deep breath and do the wet dog wiggle to shake out the extra excited energy. Elmo's body feels calmer and he's ready to use his gentle voice and quiet body to teach Tango. Tango successfully learns the trick and plays hide-and-seek with Elmo.
