Ep 18. Susan Strong

In season 2 episode 18 of Adventure Time with Finn and Jake, titled Susan Strong, viewers are introduced to a group of underground creatures known as the "Hyoomans." The episode begins with Finn and Jake discovering a small tribe of these creatures in the sewers beneath the candy kingdom. The Hyoomans are led by a fierce and determined young woman named Susan Strong, who is the only one among them capable of speaking in complete sentences.

When Finn and Jake first encounter Susan and her tribe, they mistake them for zombies and attack them with their swords.

Throughout the episode, Finn and Jake work to help the Hyoomans with various tasks and to teach them basic human skills, such as walking upright and using utensils.

However, Susan ultimately decides to stay with her people and help them rebuild their community.

When he tries to confront her about this, Susan becomes defensive and insists that she is simply a member of her tribe.

The climax of the episode sees Finn and Jake helping Susan and the Hyoomans defend their home from an invasion by the candy kingdom. Together, they are able to fight off the attackers and save their village from certain destruction. In the end, Finn and Jake say their goodbyes to Susan and the Hyoomans, promising to return and visit them in the future.
