Being Filthy, they turn the lights on a start to Sing as they both Strip for baths. They both have a Bubble Bath as they are Neighbor Bathing. While Kei is laying in her bathtub holding out a Bath Kick she has a discussion with Yuri who is Shampooing her hair over in her bathtub. As Kei is Arm Resing, she discusses that the last time she had a bath during a mission was an Off Screen Bath where to perverted old men named Jekyll and Hyde saw her.

Meanwhile above them through the air vents, Carson D. Carson is watching them during their baths but then accidently breaks the vent startling the ladies and falling into Yuri's tub. As Carson fell clothed into Yuri's bath, the water made a big enough splash that it rinsed the shampoo out of her hair but then when she sees Carson she quickly covers her chest and screams following by a swift bath kick launching him out of the tub. As Carson flies out of Yuri's bathtub, he then falls into Kei's tub landing face first right into the area of Kei's crotch. When getting up, Kei gets angry and threatens him as he is seen grabbing her breasts. While back over in Yuri's bathtub, she is seen covering her breasts with one hand and attempting to grab the orange towel hung on the rack right outside the tub but Carson who was punched by Kei flys by quickly startling her. As Carson is knocked on the other side of the room, both of the ladies are seen out of their tubs with Yuri wearing an orange Towel and Kei wearing a green Towel Bikini. After they have a discussion, alien-like creatures come and put them into some Action Bathing. During the commotion, Yuri who is still wearing a towel hangs onto a pipe above the tubs but its gets broken causing her to fall back into one of the bathtubs where she ends up Towel Bathing. She quickly backs out while panicking as the alien thats after her puches the bathtub over. For the majority of the film, Yuri remains in the orange towel after turning it into a Towel Bikini.

Later on, Professor Wattsman is seen having a strange Bath in a tub full of pink balls.
