Optimus Prime walked into what looks like a shower version of a carwash covered in mud. "That is the last time I play football in the rain with Bulkhead. Everytime he lands in the mud, he makes a BIG mess." He stood underneath a faucet, pulled the curtain, and turned on the knob. And hot water trickled down on his chassis. He was minding his own business when he heard a clanging sound coming from outside the shower room. "Hello? Is some bot there?" No one answered. He continued washing off the mud.
To calm down his nerves, Optimus turned on the radio embedded in the wall. The radio was playing an old 1980's song and he starts to sing along with the chorus. But then, another clanging sound made him jump, because it was louder than the last one.
"Okay, I'm definitely not imagining it."
He couldn't move. Optimus sees a shadow-like figure behind the curtain getting closer and closer. It was holding up a sharp weapon in one servo.
"Ahhhhhhhhhh!" Optimus slipped and fell over, grabbing the curtain, and accidentally tore it off the banner. He panicked, trying to get it off him and escape. Someone pulled it off him and said,
"Calm down Prime. Sheesh, you sounded like you saw a ghost." It turned out to be Ratchet, he too was covered with mud, and he was actually holding a large brush. Optimus sighed in relief.
"By the way, nice pipes." He suddenly felt embarrassed after Ratchet made that comment.
