The five-hundred & twentieth issue of MAD Magazine has multiple features parodying Adventure Time. The first of which is the issue's cover that depicts Finn as Alfred E. Neuman, while some of the show's major characters (such as Jake, Princess Bubblegum, BMO, Lady Rainicorn, and Snail) are shocked and dismayed by this revelation.
Later in the magazine is an article titled The 50 Worst Things About Cartoons. Number One on the list is the fact that Adventure Time is bizarre and trippy. An image headlining the article features many characters from the show rendered in an abstract style, as a viewer goes insane in the center.
The final Adventure Time-themed feature is a game called MAD'S Do-It-Yourself Adventure Time Episode. This template has been used in previous MAD issues that featured subjects such as Twilight and Batman. The reader must pick one box from each category to make a nonsensical Adventure Time plot.This, however, is not the first time Adventure Time appeared on MAD Magazine. In issue five-hundred & eighteen (Twilight Spoof) on page 19, on the top right corner after the man made a bubble saying "...but THAT lady gives me the creeps!" one can see Marceline taking one of her fangs out of her mouth.
The online forum and game site Gaia Online teamed up with Adventure Time creators to create virtual items. First, a chance item (CI) called "Adventure Time & The Quest for Knowing" will lead the Gaia player on a quest with Finn and Jake, which will lead to exclusive items themed around Adventure Time characters. There are three deluxe items that re-imagine Adventure Time characters in Gaia style: Sugar Royalty, Mathematical Knight and Vampire Sound. The game also introduced an Adventure Time forum and live hangout, plus an interview with the show's creator, Pendleton Ward, which occurred at 6pm PT on March 22, 2012. Also, one of the owners of the "Factori" as of October is dressed as BMO.

Captain America, Iron Man, Thor, and the Hulk have defeated the Red Skull and got the Cosmic Cube away from him. When Iron Man warns that the Cosmic Cube can be dangerous, Captain America says that he wants everything to be simpler again, and suddenly, the Avengers are in sixties animation, much to their dismay. Iron Man then takes the Cosmic Cube and says that he wants to get back home, but also mentions "short and sweet." Soon, the Avengers appear in "Super Hero Squad," and the Hulk takes the Cosmic Cube to get home, but mentions the word "time." The Avengers now appear in "Adventure Time" animation.
Thor's hammer is now a lollipop and Hulk has turned into a dog. Hulk suddenly develops long legs and runs away with joy of his new power, much to the others' dismay. Suddenly, they are attacked by a giant waffle monster, and Iron Man tries to stop it, but learns that he can only shoot rainbows and glitter, so they run away. They try to start looking for Hulk so they can return home with the Cosmic Cube, but are suddenly warned by a gnome that the Ice King is coming. They confuse Ice King for help and they are suddenly approached by him, who asks if they have Princess Bubblegum. When they respond no, Ice King freezes Captain America in a block of ice, which Iron Man criticizes on.In his mind, Captain America meets the Watcher on the moon and the Watcher tells him that they are in the Cartoon Network series Adventure Time and that they must return to their own time, otherwise they will be stuck there forever. This is referring to the animated short when Finn's mind is transported back in time and to Mars with Abraham Lincoln. They then discuss the possible success of MAD before Captain America busts out of his iceberg and finds Iron Man and Thor playing a card game. Suddenly, Hulk comes back and says that he was with Princess Bubblegum but wants to go home as their new relationship is "complicated." At the mere mention of the word "home," the Avengers return to their own time and animation. They vow to never speak of Adventure Time again, but are dismayed that Hulk has brought Finn and Jake with them, and they now appear as a super-powered Batman and the Thing.

In the episode "Papa / 1600 Finn" which aired on May 13, 2013, Finn and Jake move into the White House because that's where Finn's dad, President Dale Gilcrest, lives. Dale apparently sent Finn to make him grow up, but he doesn't want him beating up wizards and kissing hot fire ladies so he brought Finn back. Dale tells Finn to keep out of trouble while someone comes over for a meeting. However, the 'someone' is the Ice King, so, naturally, Finn attacks. Dale tells Finn it's ok. Later, the Ice King is speaking about freezing the whole world, so Finn starts attacking again until Dale explains that's the plan to stop Global Warming. Finn goes out of the White House and sits, facing away, saying that maybe the Ice King actually is a good guy. Behind Finn, we see the Ice King freeze Dale, then kicks the White House. Jake tells Finn that, but Finn says that it's probably all part of the plan. An alien ship lowers itself over the White House and blasts it to bits. Jake tells Finn this too, to which Finn says 'Shmowzow!' Then he says it's still part of the plan.
