Party Monsters is the twenty-first episode of Power Rangers Samurai, co-written by Amit Bhaumik. The episode is notable for being a "Clip Show" and "Halloween Special". The episode features an original storyline, not based on any episode on Samurai Sentai Shinkenger, focused on the monsters destroyed by the Samurai Rangers. Despite its original story, Yasuko Kobayashi (the head writer of Shinkenger) is still credited among the writers for the episode.
In the Nighlok afterlife, the defeated Nighlok Monsters hold a Halloween party and recap their battles with their Rangers to each other.
In the Nighlok Heaven, a Nighlok knocks on the door and gives the password. He is greeted in the Spookeasy Club and their Halloween Party. The Nighloks are having a party and wishing each other Happy Halloween. Negatron is bummed that they are all ghosts. They decide to share each of their stories against the Rangers. Madimot is the first one to reveal his story.
At the Sanzu River, Master Xandred is depressed from his failures. Back at the Party, the Nighloks continue their party. Dreadhead shows off his Red Ranger pumpkin followed by his story. Antberry shares his story against the Blue and Gold Rangers. Yamiror goes next with his story. Back at the Sanzu River, Octoroo and Dayu try to cheer up Master Xandred.
The stories continue with Desperaino and Rofer. Negatron gets his chance to share his story. Moogers join the party with their own costumes. One of the Moogers is dressed as the Samurai Megazord. Steeleto and Vulpes share their stories. The Sanzu River punch bowl is now emptied. Splitface shares his story of his Mega fight.
Dreadhead talks about his battle against the Beetle Cannon. Rhinosnorus shares his brief story about exploding behind the Blue Ranger. Tooya shares his story against the Red Ranger. The Nighloks reveal how they were defeated. The party ends before Master Xandred can pay a visit. Octoroot states that the party was for those in the Nighlok obituary only.

- Right when the Nighlok comment on every time they were defeated, they comment on a Super Sentai quirk where the heroes defeats the monsters, and the heroes turn and pose when the monsters explode.
- This episode creates a continuity problem with Dayu, who was shown to leave after Master Xandred damaged her harmonium (which can be seen intact in this episode). Although it could be said this episode takes place before these events, this cannot be either as Rhinosnorus is seen amongst the party's guests (this monster was destroyed after Dayu's departure).
