Oh, look! A Random Adventure Time with Fionna and Cake drabble.
Bubba stared at the slim slivers of light that managed to peak around the thick curtains and murmured, "You don't really like red."
"What?" Marshall cracked an eye open to stare. He loved his boyfriend, but he realy hated the random pillow talk. No male should be able to process that much information post coital so soon. It was wrong.
"Color is merely a reflection of the spectrum wavelength that is not absorbed. So, technically, you like every color except variations red," Bubba hummed as he drew patterns across his partner's skin.
"Bubba?" Marshall sighed. He considered that it might not be possible for Bubba Gumball to shut off his ridiculous nerd brain. Maybe he had simply interrupted it's normal flow. Thus, the randomness was spewed.
"Yes?"
"Shut up or I'll kill you."
"Mmmm," Bubba smiled into his lover's hair and the pair went to sleep like normal hormonal teenagers.
No, I really have no idea. Hopefully, it at least amused you.
