Abracadaniel first appears in the episode "Wizard Battle." He enters Wizard Battle in the hopes of winning money, but when he learns that the prize is a kiss from Princess Bubblegum, he resigns himself to be killed by another wizard. Finn and Jake (as Magic Fist) promise to help him win when they learn he has no interest in kissing the princess. To win Wizard Battle, Abracadaniel transforms Ice King's nunchaku into a living butterfly. When the transformed butterfly flies above Ice King, Abracadaniel transforms it back into nunchaku, after which it falls on Ice King and knocks him out. Because Abracadaniel beats Ice King and won the Wizard Battle, he determines that he had become a man and wants the kiss from Princess Bubblegum. A shocked Finn screams viciously in his face, knocking him out and causing him to lose the Wizard Battle.
Abracadaniel later returns in "Wizards Only, Fools" when he is about to be sacrificed by Bufo, Laser Wizard, and Forest Wizard, but he is arrested by the Wizard Police along with Finn, Jake, and Princess Bubblegum. Later, in the prison, he challenges Princess Bubblegum to a duel to the death, but loses. He is frozen after she uses the cold spell, and is transported back to the Candy Kingdom in order to distract Starchy while Princess Bubblegum gives him the antidote for his cold.
He returns again in "Play Date," where Finn and Jake try to make him and Ice King become friends, and, therefore, cause Ice King to move out of their house. Though Ice King is initially wary, he and Abracadaniel (nicknamed "ABD" by Finn) soon become close friends and perform a show for Finn, Jake and BMO. However, the plan backfires when Abracadaniel also stays at the Tree Fort with Ice King, and they inadvertently summon Kee-Oth the Blood Demon, who threatens to kill them before kidnapping Jake. In the end, Ice King and Abracadaniel stay friends and go off to hang out in the rebuilt Ice Kingdom, while Finn is left disconsolate over the missing Jake.
He then returns in Thanks for the Crabapples, Giuseppe, who is driving the Ice King and a band of wizard misfits on a bus on a mystical road trip. He and Ice King trade headgear and he creates an ice road so the bus can continue to move without using wheels.
Abracadaniel is a humanoid with a pear-shaped head and pink skin. He has black hair that goes around his whole head. He wears a white robe and socks, as well as a rainbow headband and what appears to a small blue fanny pack that sports a red and yellow lightning bolt design on its rear. His robe is a bit odd-looking; it is long-sleeved and forms circular bulbs at the top of his legs. There are green spots at the bottom of the legs and the end of the socks. There is also a green circle on the chest area of the robe. He wields a small wand that forks at the end; it is brown and essentially looks like a twig.
Abracadaniel can produce rainbows from his wand. Like Rainicorns, he has the power to change someone's color. Abracadaniel states his body is soft and squishy; this enabled him to survive being hit by a meteorite summoned by a Rock Wizard. He can also transform things into butterflies and back. The theme of his powers seems to be that they are harmless on their own. Abracadaniel's spells are called "cantrips" (he once actually says "cantrip" as he casts a spell). These easily mastered magic tricks include but are not limited to the ability to transform small objects, create different colored lights, and to change the skin color of an individual (prestidigitation).
- "All the Little People" (as a toy)
- Abracadaniel has been shown to have difficulty exercising his magical powers, groaning in exertion when he produces a rainbow, for example. This could be for any number of reasons, but it seems that it stems from simply not being very good.
- Abracadaniel was able to put on Ice King's crown without going insane in "Thanks for the Crabapples, Guiseppe". This is likely due to him being magical himself, just as Jake was unaffected when he put it on after destroying Ice King's "invincible armor" and retrieving his and Finn's sandwiches. However, unlike Jake, he is shown using the Ice Powers himself.
