Zach wants to spend his summer hanging around the house, but his mom challenges him to play outside and use his imagination. Zach is convinced this will be a boring summer, but then his best buddy Sprocket, a bullfrog, comes up with the exciting idea to build a time machine. Zach asks his friend Bella to help them build it, and when it's ready to go, they start the engines and zoom into space. After that, they go back in time to the Garden of Eden, and then, they watch the animals going into Noah's Ark. They make it home in time for dinner, and Zach and Sprocket can't wait to see where the time machine will take them the next day. This will be the best summer ever
