The Johnny Test Theme Song 1 is the first theme song used in the Johnny Test cartoon. It was used only during the first season, from the episode Johnny to the Center of the Earth, up until the first season's finale, Johnny and the Attack of the Monster Truck, running exactly 26 episodes.


The theme song starts with a countdown, and, as it reaches 0, the words Johnny, followed by Test, blink a few times. Then, the radioactivity sign is shown, becoming lower. Johnny drops from the top of the screen and lands atop the sign, and, after it spins a few degrees, Johnny takes off with the Turbo Action Backpack, flying to the lab, where he takes a radioactive chewing gum created by his sisters. As he eats it, he changes to Johnny X, and uses the hurricane hands to make the lab a mess. Dukey is than shown laughing, as Johnny rides Scoots, and stops near him.

Dukey jumps on scoots, and they leave the lab, passing through Lila's room, who is working on the pc, and through the kitchen, which Hugh tries to make it shine, finally reaching upstairs, to the door to Johnny's room. As Johnny opens the room, a lot of junk comes out of it, including a surf board, which Johnny uses to surf on the junk.

The scene then shows Bling-Bling Boy, Zizrar the Mole King, Mr. Black and Mr. White, the Extreme Teen Team, the Moonsies, Brain Freezer, Monkey Gil, the Turbo Toy Force, and RoadBurn.

The scene then shows Johnny singing, while transforming into different forms, Ninja Johnny, Deep Sea Johnny, King of the Sea, Mega Muscle Johnny, Hairy Johnny, Astronaut Johnny, Girl Johnny, Monster Johnny, and than back to Johnny, who continues singing. Dukey is than shown playing Johnny's guitar, and singing along with Johnny, before he smashes it on the ground, breaking it, and the scene cuts back to the lab where Mary has her arms crossed as Susan pulls the lever down making the screen white and the Johnny Test logo appears.
