The short focuses on a boy named Pen (the character who would later be
renamed Finn) and a dog named Jake as they learn from Lady Rainicorn
that the Ice King has kidnapped Princess Bubblegum, in the hope of
marrying her. Declaring that it's "Adventure Time", Pen and Jake set off
for the Ice King's mountain lair. Pen and the Ice King fight while Jake
remains outside flirting with Lady Rainicorn, ignoring the battle. Just
when Pen seems to be gaining the upper hand, the Ice King uses his
"frozen lightning bolts" to freeze Pen in a block of ice. For
unexplained reasons, this transports Pen's mind "back in time, and to
Mars" where he has a short motivational conversation with Abraham Lincoln.
After being told to believe in himself, Pen is returned to the present,
just in time to see the Ice King fly away with Princess Bubblegum.
Chasing after him using Jake's extendable legs, Pen rescues the princess
from the Ice King's grasp. Jake pushes the magical crown off the Ice
King's head, thereby removing the King's source of power. The Ice King
then plummets off screen, yelling a long list of complex threats of
things he will do when he returns. The story closes with Princess
Bubblegum giving Pen a kiss, which he enjoys but which embarrasses him
greatly. He attempts to leave, but Jake claims that they have nowhere
else to go and that there are no adventures that need them. Fortunately,
some nearby ninjas are stealing an old man's diamonds, and they both
run off in pursuit. (Adventure Time Pilot from Wikipedia)
