Johnny Test Wiki

The Johnny Test Theme Song 2 is the second theme song used in the Johnny Test cartoon. In Canada, it was used ever since Season 2's premiere, Hoist the Johnny Roger/Johnny's Turbo Toy Force, up to Season 4's finale, Good Ol' Johnny Test, running 103 episodes. In the United States, it was used on Season 4 episodes, Cartoon Network and Netflix airings of the second and third seasons, and streaming service copies of the first season (excluding the Mill Creek Entertainment DVD releases of Johnny to the Center of the Earth and Johnny X).


Like in the last theme song, this theme song also 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 than jumps on it, 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 intro than shows clips from random episodes from Season 2, clips shown up until the ending on the theme, which is also taken from the old theme song, with Dukey breaking the guitar.

  • Half the intro is composed of clips from Johnny Test episodes exclusively from season 2, while the other half is composed of animations recycled from the first theme song.
  • Another difference is that at the end, it has a different logo. It's almost the same except it has a blue background and the logo contains a more gradient effect. The screen looks more different in the third theme song.
  • Since the show switched production from the United States to Canada, the theme song had to be changed for Canadian broadcasts because of CanCon laws. This theme song in general sounds suspiciously similar to Green Day's "American Idiot" or Weird "Al" Yankovic's "Canadian Idiot." Coincidentally, Johnny Test is an American-Canadian show.
  • On Netflix and other digital platforms, this theme song is also used in Season 1.
  • In the U.S., this theme song was not used until post-S2 episodes of Johnny Test started airing on Cartoon Network, likely using the original Canadian prints because of it.
  • If you listen closely in the part where the singer sings Johnny's full name twice (Johnny Test, Johnny Test...), you would also hear other singers singing in the background the lyrics "This is the life of a boy named Johnny (2x)..." It is clearly heard in the French version of the song, as well as the tune being played in the beginning of the credits song.
  • On widescreen copies of seasons 2-4, much of the theme song is cropped to 16:9, while the Johnny Test screen is shown in true 16:9.
