Adventure Time Theme Song

thumb|300px|Adventure Time opening. The Adventure Time Theme Song and opening title sequence shows all of the main characters and some minor characters. It has the same lyrics as the Animated Short but is slightly different. It starts with a view of a post-apocalyptic wasteland with several nuclear weapons clearly visible, then shows a rookery of penguins, then moves to the Ice Kingdom, then shows Ice King, then the Candy Kingdom, then Princess Bubblegum riding Lady Rainicorn, then Marceline, and ends at Finn and Jake's Tree Fort. When they pound their knuckles together, the theme song begins. The song itself is sung and played by series creator Pendleton Ward. It ends when Finn and Jake are climbing a mountain. Finn climbs to the top and strikes a pose, and Jake lays down near Finn as the show begins.

Production notes

 * A character peeping over the balcony of the Candy Castle can be seen briefly. According to Pen Ward, this is a cameo by Gingerbread Muto, the Candy Person version of storyboard artist Adam Muto. Pen says he puts Adam in most of his films because it "riles him up."
 * The final shot with Finn and Jake posed on a mountain was inspired by the fantasy art of Frank Frazetta.
 * The beginning of the sequence, with the rising musical tone and flying over the landscape was inspired by the opening sequences of The Simpsons and Pee-wee's Playhouse.
 * Pen states: "If you listen carefully to the recording, you can actually hear Derek Drymon typing on a keyboard in the bit when Jake is walking... a little clickity clack in that wide shot when his legs are stretched out. I recorded the lyrics for the opening title in the animatics room where we have this little crummy microphone JUST so that we could add it to the titles and submit it to the network. Later, we tried re-recording it and I didn't like it... I only liked the temp one."

Trivia

 * During the post-apocalyptic wasteland scene, for a brief moment you can see a grey arm with purple spots and a chew mark,coming out from the log with an axe stucked and arrows. It could be a mutant or a zombie. It may be a surviving human. Natasha Allegri stated that it was a zombie arm.
 * Also during that scene, Bubblegum's communication device from The other tarts can be seen hanging from a tree.
