Author's note: Okay, I have my doubts that Otto is this oblivious in the show, but let just say for the sake of this of this fic and the fun of it that he is. Now that is covered let's get to the fan fic.

"Awww!" The green cybernetic monkey knelt down at tabby. "Can we keep him Gibson?!"

"No Otto, we can't pick up any random stray;" A blue cybernetic monkey answered hold a paper bag. The duo and their team seemed to have the day off so Gibson decided it was the best time to get a few items from the grocery store for his experiments, while Otto needed to get out, to much of the blue monkey's annoyance.

"Awww! Come on Gibson, he probably won't eat much and he's cute!"

"No Otto! Now put her down, we need get back!"

"Her?"

"He's a she Otto;"

"Really?..." The green monkey asked with a baffled face before looking at the cat, holding her like a baby. "How could you tell?" At that moment, a tint of pink peered through the fur on Gibson's cheeks. If there was two things that the blue monkey regretted on doing, it was one: not telling his green brother how to differentiate between a girl and a boy mammal and, two: mentioning the feline's gender. Though they have been around humans, humanoids, and androids, even having a teammate of theirs that is a male human before and they are usually easy to tell, but other mammals like cats and dog, not much and the green simian was not known for awareness of his surroundings.

The slight blushing monkey made a soft coughed into a fist before he spoke up. "Yes well... we better get back;" He walked while Otto put down the cat and followed.

Once they gotten back home that was a giant robot they go off their separate ways. Otto started going through the hallways until, he ran into his human teammate, Chiro. "Hey Chiro!" He called out in a cheerful tone.

"Hey Otto, what's up?"

"Do know how to tell a girl kitty from boy kitty?"

"Oh uh?..." The boy uttered, rubbing his hand on the back of his head, looking away from the monkey with pink dusted face. "Gee Otto... I would, but I got something to do. How about asking one of the others?""

"Okay; Hey, maybe Sprx could tell me?!"

"Ah, Sure?!"

"I going go find him, thanks Chiro!" Otto soon dashed off.

He searched around until he found both the red monkey simian, he was looking for and his only female teammate Nova. "Hey Nova, Sprx?!"

"Oh, hey Otto;"

"Ha ha, hey Otto, what's up?!" Sprx greeted.

"Do you know how to tell a girl kitty from a boy kitty?"

"Ha ha, well..."The red monkey started saying with a cocky pose, before Nova slapped him on the face with her tail.

"Shut it Spx, you don't know; maybe you want to asked Antauri or Gibson?"

"Okay." Otto then gone off to find black fur simian.

It took a while, but he met with his friend. "Hey Antauri, you know how to tell a girl kitty from a boy kitty?!"

At that moment, on to his fist as his cheeks turned a slight shade of pink like Gibson's did, before suggesting "Perhaps, Gibson could answer your question?" The green one put his head down in defeat after attempts of getting the black monkey to answer his question and failed. He soon went off to find his blue companion again.

When he met up with Gibson again, Otto tried begging to, which the blue simian gave up, sigh, mumbled "Fine;" cupped his hands mouth close to the green monkey's ear, and whispered.

"Ah?! Their...?"

At that moment Gibson covered Otto's mouth shut and answered "Yes Otto, that;" with a blush face.

A day later, Gibson had to go out again to grab some stuff he forgot and Otto wanted to go with him. As the duo heading back, the green simian soon spotted a mother cat with her kittens and asked "Uh, Gibson where do babies come from?!" The blue monkey soon froze as his cheeks soon lit a bright red making him look like Sprx.
