theme: water pistols
"Psssst. Eileen," a familiar voice whispered from underneath the inflatable pool toy.
She turned around. "Rigby?"
He reached out and swiped her arm, dragging her underneath the floaty.
They both wound up poking their heads through the hole in the center.
"I picked you to be my partner in crime," he informed her, grinning.
"What?"
Rigby revealed to have two water guns in his free paw.
"I didn't pick Mordecai because he's being sort of a killjoy today," he explained, giving her a gun.
"So the best way to deal with killjoys is to get them aaaallll wet."
Rigby snickered. "They'll never see it coming," he added.
Eileen positioned her goggles to her hairline, leaving redish circles to encompass her eyes.
She plunged her pistol into the water, pumping it full of ammo.
"Let's do this," she said.
Rigby and Eileen dove back underwater and headed towards the deep end.
Not so far away, Mordecai had his back turned, sitting on the edge of a pool chair. He was babbling noisily to Thomas.
"Here's our chance," he murmured, situating his water pistol to Mordecai's back.
Eileen mirrored his actions.
"Ready..." he started, placing his finger on the trigger. "Aim... FIRE!"
Water shot out of both the guns, managing to soak Mordecai from head to toe.
He turned around.
"Rigby?! Ugh, I should of known. Look, all I said was I'd play Dig Champs with you tomorrow. Stop being such a baby about it."
"Whatever, man. I don't even need you to have fun!"
Rigby took a deep breath and ducked back under. Eileen supposed that she was to follow him, so she did the same.
He retreated to a corner of the pool, rising up for more air.
Eileen looked a bit worried.
"Are you okay?"
"Yeah, I'm fine," he muttered. "It's just..."
"What?"
"Sometimes Mordecai just straight out refuses to do stuff with me. He tells me to be 'responsible' and all that crap. I just miss how it used to be when we were kids," he explained. "And now he's growing up, and I'm still behind."
"Rigby," Eileen replied, putting a hand on his shoulder.
"Who said that Mordecai was moving on without you? He'd never do that. Just because he wants to be mature on occasion doesn't mean he wants to stop being your friend," she told him.
"Plus, you'd have me to be for you, too."
She offered him a smile.
Rigby eased his way out of the corner.
"I guess you're right," he admitted.
"You know how I can thank-you, Eileen?"
"Hm?"
Rigby pulled the water pistol back out and squirted, saturating Eileen's rose-tinted bathing suit.
She laughed, spraying him with water as well.
