Vampire Orientation

Vampire Orientation was created by Marceline in "Heat Signature" in order to further prank Finn and Jake after her Biting Ritual.

Trials
Vampire Orientation consisted of several trials for a fledgling vampire to complete in order to come into their newly found powers.

Trial 1: Invisibility
The first trial was to use their new powers and become invisible. Marceline told Finn and Jake that the best way to do so was to spin in circles and chant "invisible." She did this to humiliate the two, which lead to further pranking when the two attempted to frighten LSP.

Trial 2: Toughness Test
This segment of the orientation was merely an excuse to beat up Finn and Jake.

Trial 3: Spooky Vampire Walk
Marceline hastily made this segment up because she did not want Finn and Jake to hurt themselves by trying to fly. She used the excuse that it was a too advanced technique.

Trial 4: Flight
Wendy, Booboo and Georgy convinced Marceline they had a plan for faking the flight, so they went to the top of a nearby tower where Finn and Jake were told to jump off. The ghosts reveal they have no plan, and Marceline fast-falls to save them (while invisible) allowing Finn and Jake to complete Orientation still in-tact and believing they're vampires.
