Andrew spotted his sister Fionna browsing the book store. He snuck up behind her and aimed the squirt gun. She turned around just before he fired, resulting in the water squirting her directly in the face.
She yelled out, half in annoyance, half in anger over what Andrew had done.
"Oh my God Andrew, what the hell is the matter with you," she said.
Andrew was about to laugh before his laughter turned to horror. He gasped as Fionna's skin began turning gray and taking on a texture much more suited to a hide then soft human skin.
Fionna gasped and hugged her belly as she grimmest.
"What did you do to me?"
Andrew looked at the squirt gun and shrugged his shoulders.
"I didn't do anything," he said.
The sight before Andrew however told a different story. Andrew hoped that whatever was happened to her would stop, that she would be fine.
She wasn't.
Before Andrew's horrified eyes, Fionna's body expanded. Her clothes strained and tore at the seams. His sister released her hug and looked at her hands to see that they were swelling.
Tears streamed down her face as she looked at Andrew with begging eyes.
"Get help," she cried.
Logic told Andrew to run for help. Someone would be able to reverse this, it was all for fun, right? The arcade seemed the best place to summon help.
"Oh God, no," Fionna cried.
Andrew watched as Fionna's nose started getting longer. He wanted it to stop, he begged whatever was causing this to leave Fionna alone, that squirting her was a bad joke. If he repented somehow, that was supposed to make things right, wasn't it?
It didn't.
Fionna's nose grew into a truck before Andrew's terrified eyes. Other shoppers were starting to flee in terror.
Andrew ran to get help but didn't get far before he heard a loud rip. He turned to see that Fionna was growing mass from who knows where by the second. Her hands were thick and hoof like and her ears were getting much bigger.
A look at the squirt gun confirmed it, Fionna was turning into an elephant. The squirt gun turned anyone Andrew squirted into an elephant. The idea was absurd but there it was playing out in front of him.
"Damn you Andrew! Why did you..."
Fionna's voice was much deeper.
"Why did..."
Fionna screamed a scream that in the span of a few seconds changed from a scream to the bellow of an elephant. It was so loud that Andrew had to cover his ears as glass windows shattered all around them.
Andrew now watched as Fionna fell onto all fours. Her growing back legs and hooves had since destroyed her pants and shoes. The body shape that was now hers was nothing even close to human. It's was rounder and much larger.
When Andrew tried to run he felt the ground shake before him. Something picked him up and turned him around. It was Fionna picking Andrew up with her truck. Fionna was an elephant.
"Please Fionna, I did know this would happened to you," Andrew cried. "Please don't kill me!"
Andrew knew he'd have to think fast.
"I'll go back to the arcade and get help! They'll change you back!"
Fionna lowered Andrew to the ground.
"Just stay here okay?" Andrew asked.
