Ep 21. Ignition Point

Finn and Jake are back in action in season 4 episode 21 of Adventure Time. This time around, they are on a mission to save the Fire Kingdom from destruction. The episode, entitled "Ignition Point," centers around Finn and Jake's efforts to find a way to extinguish a raging inferno that threatens to destroy the entire kingdom.

The Fire Kingdom is in peril, as its ruler, Flame Princess, has accidentally ignited the volatile and highly flammable Pyrotechnics Guild Hall. Her father, the Flame King, is convinced that the only way to save the kingdom is to sacrifice his daughter to the flames and appease the fiery gods that rule over their land.

Finn and Jake, however, are not willing to let that happen. They embark on a dangerous quest to find a way to put out the flames and save the princess and her kingdom. Along the way, they encounter a number of challenges and obstacles, including the treacherous Fire Count and a horde of pyrotechnic ninjas.

Despite these challenges, Finn and Jake manage to come up with a plan to douse the flames and save the day. With the help of their trusty flame-retardant suits and some quick thinking, they are able to infiltrate the Pyrotechnics Guild Hall and put out the fire before it can spread any further.

As they make their way back to the Flame Kingdom, Finn and Jake are hailed as heroes. The Flame King, impressed by their bravery, declares them honorary members of the Fire Kingdom and awards them with a special flame-shaped medal.

Overall, "Ignition Point" is a fast-paced and action-packed episode that showcases the best of Finn and Jake's heroic abilities. It's a great addition to the Adventure Time canon, and a must-watch for fans of the series.
