Steve came up with a device to use to change the channel on the television without getting up, but when he realizes that there's already such a thing, it spurs him to try and create a unique invention following the slogan of ""try again."" When Mr. Salt and Mrs. Pepper want to eat peanut butter and jelly on bread together, Steve's excited at his solution, only to realize that the ""sandwich"" already exists. We come across Shovel and Pail and play an invention game. We take a look at pictures of inventions and identify the order in which they were invented. Later, we skiddoo into an invention factory, where we take a look at some famous inventions such as a train and a car.
