When the show's title is seen, Finn (without his green backpack) and Jake float up using feathered wings sticking out from their backs while holding a white piece of cloth that says with Finn and Jake. This entire ordeal occurs approximately within the span of 12 seconds. Finally, they pound their fists together and a loud smashing sound is heard as the theme song begins. The ending shows Finn and Jake's Tree Fort and then the two of them inside. Then outside of Finn and Jake's treehouse is the two-headed duck. She turns and hisses at the audience while showing her pointy teeth. The camera then pans to the right, and zooms into a mountain range showing Marceline playing her Fender Precision BassВ while sitting outside of her cave. After that, the camera quickly scales Princess Bubblegum's Castle, eventually passing the clouds to where we can see Princess Bubblegum as she smiles and waves while riding on the back of Lady Rainicorn. It shows the Candy Kingdom and a large crowd of Candy People laughing and dancing in the middle of the road.

Then the rest of the Ice Kingdom appears including Ice King flying next to his lair, spinning around to face the screen while activating his Ice Powers with his hands.

Next, in a snow-covered biome, are shown penguins, including Gunter and two other penguins hugging (with a tiny red heart floating above their heads) that make a few quick quacking sounds, and a Snow Golem sitting on a grassy hill nearby. The opening title sequence starts with a view of a post-apocalyptic wasteland that features a rat inside of a broken television and several undetonated nuclear bombs. 6.2 Differences between the two intros (Original and sex-swapped).
