Episode Title:
The Crew Builds a Solar-Powered Bus / The Crew Builds a Lifeguard Tower
Episode Description:
As Wheeler tests his new solar-powered tablet in the park with Rubble, Mix, and Charger present, they get a call from Sierra Sparkle who informs them that she has written a new song about nature which she will perform on the top of Tooltop Mountain. As there's no parking spaces on Tooltop Mountain, Rubble plans to have Camilla deliver an electric bus as they work on building a bus station. Speed Meister overhears the discussion and plans to commandeer the bus and drive it up the mountain. After the bus station is built, Camilla brings the electric bus in as it is plugged in to the charging station. As Rubble & Crew work on building bus stops, Speed Meister and Mr. McTurtle steal the bus when it wasn't fully charged. After the bus rans out of power halfway up to Tooltop Mountain, Rubble saves Speed Meister who accidentally backs into the charging station causing Rubble & Crew to hybridize the electric bus into a solar-powered bus.
At the Bark Yard, Rubble, Mix, Charger, Wheeler, and Motor are preparing for a beach day. They each pack up the different beach day items. Upon their arrival at the beach, they meet up with Coach Karima who has become Builder Cove's new lifeguard. When Motor's rubber duck Ducky ends up lost during the game of frisbee, Mix and Charger get the idea to build a lifeguard tower to help look for it. Using extra material from Wheeler's truck, Rubble & Crew construct a lifeguard tower. Once the lifeguard tower is built as high as it can complete with a slide and a big shade, Coach Karima spots Ducky in the waves as Coach Karima works to save Ducky.
