Living room picture: The evolution of a wheel thought the episode, First a stone wheel, then a wooden wagon, then a metal gear, then a bicycle wheel, then an automotive wheel + tire
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 he asked Blue if she invented something, she replied that she did, and the play Blue's Clues to figure out what that invention is. After getting his notebook from Sidetable Drawer, he sees Blue's pawprint on it. This means that Steve's notebook is the first clue, so he draws it in his notebook. Immediately after the first clue, Steve meets up with Mr. Salt and Mrs. Pepper, who want to eat peanut butter and jelly on bread together. Steve's excited at his solution: the peanut butter and jelly sandwich, only to realize that it already exists. Then they 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. After finding the second clue on the Thinking Chair, they skidoo into an invention factory, where they take a look at some famous inventions such as a train and a car. Before he skidooed back home, Steve found the third clue on a picture of pawprints. When they got home they find that the very game they were playing is the answer and that Blue invented it. So Steve decide to invent a handy dandy notebook holder.
This marks the only time there's a clue before Steve does the Song.
This is also the earliest time a clue is found, when Steve got the notebook (the clue) from Sidetable Drawer.
Judging by Sidetable's laughter, she already knew it was a clue before Steve did.
This is the third time Steve draws his notebook in his notebook.
