Dog Day Engineers

COLD OPEN 	Big Bird and Grover set up today's theme of engineers, having engineered a large block tower (which topples over).
(First: Episode 4920)
	SCENE 1 	Nina has her hands full tending to the Bike Shop, studying, and watching after some fetch-loving dogs. Rosita and Zoe (still with a broken arm) come by, wishing to ride a tandem bike. The only one available has a missing wheel, meaning it can only be peddled for now. Grover rushes over with an urgent repair problem at the laundromat. Zoe and Rosita offer to watch and play with the dogs while Nina goes to help Grover.
	SCENE 1 cont'd	Grover shows Nina a malfunctioning washing machine, which squirts him with water. He prepares an umbrella as Nina takes a look for herself; nothing happens until Grover lets his guard down and peeks in as well.
	SCENE 1 cont'd	Meanwhile, the monsters' arms are getting tired from tossing the balls to the dogs over and over. Zoe muses that she'll have to learn to color with her feet because her arm hurts so much. Rosita brainstorms a way they can make the task easier, proposing they make a slingshot that will throw the ball instead; Zoe is unable to do such a thing with just one arm. Zoe turns one of the bike wheels, sending a stray leaf flying off it. This inspires Rosita to think of how they can apply the same principle to throwing balls instead. She comes up with a way they use the tandem bike and create a ball-throwing machine that works on peddle-power instead of tiring their arms out.
	SCENE 1 cont'd	Back at the laundromat, Nina completes work on the broken washer. Grover takes refuge outside while she tests it out. The machine works fine now, but Grover is still hit with water from Chris' hose as he washes down the Hooper's Store awning.
	SCENE 1 cont'd	Nina sees what Zoe and Rosita have done and commends their engineering work. Several more dogs show up to play fetch too.
