|This article is about a/an episode in Chouriki Sentai Ohranger.|
A sleep-inducing Machine Beast is sent to Earth but faces difficulties when Riki proves to be the only one immune to its powerful lullaby.
Bara Gusuka, a sleep-inducing Machine Beast, encounters the Baranoia royal family and makes them fall asleep with its droning, causing a nuisance. Bacchus orders it to be turned into scrap for this, finding it lazy and its powers stupid and useless. Realizing its potential, however, Hysteria decides to send it to Earth, despite Bacchus initially protesting that putting humans and robots to sleep makes it worthless. When it gets to Earth, Gusuka is successful in putting several humans to sleep, and almost does the same to a Takompas pilot.
After shooting Bara Gusuka down from its Takonpas, the Ohranger fought the Barlo Soldiers near a creek. On Acha's cue, the monster caused the Ohranger to become sleepy by repeating its name over and over in a musical manner, and Acha was ready to open fire. Before the Ohranger can be sent to the dream world, KingRanger intervened, ordering her to "stop singing her stupid song", and he dismantled Gusuka with King Victory Flash. An aging scientist, named Kotaro Henna, despondent at Gusuka's destruction, agrees to rebuild it in his robotics research facility.
Bara Gusuka is subsequently rebuilt into two forms, one with two gramophone horns on her head and later a less adorable form with a power amplifier where its face used to be. Once reassembled and activated, Gusuka begins to sing and dance around in a circle. Henna is pleased, but Gusuka's song in so sweet and calming that he immediately falls asleep. It subsequently went into Tokyo to put everyone in a deep, peaceful slumber, including two police officers and a car driver who dies in a crash as a result. Even KingRanger couldn’t stop the singing robot. Dorin and Paku showed up to help. Once Paku foiled Gusuka’s device that amplified its sound waves and made its lullaby more potent, the Ohranger quickly recuperated and everyone that was put to sleep immediately awaken and are revitalized as if nothing happened. Gusuka tries to sing again, but no sound can be heard. It is enraged.
OhRed and KingRanger defeated the Barlo, and the Ohranger unleashed the Ole Bazooka. Acha and Kocha revived their fallen comrade.
Red Puncher stunned Bara Gusuka with Puncher Gatling before Battle Formation was summoned. It was ultimately destroyed by the Super Legend Beam.
