There isn't much Mordecai Inflation out there :/ Anyhow, here's my story! I hope you enjoy! ^_^

For those who don't want to download it:

Mordecai stood himself up, holding the bottle of pills firmly in his right hand, and popping the lid off with his left hand. He turned the bottle around, reading the print on the back. “Take only one pill at a time...” he murmured to himself as he read it. He tapped the bottle onto his left palm, making 2 of the white, circular tablets fall into the centre of his soft, blue feathered hand. He shrugged slightly, “Two couldn't hurt...” he thought out loud. “Well, bottoms up!” He tilted his head back as he dropped the tablets into his mouth, quickly proceeding to wash them down with a small glass of water.

Rigby had begun 'teasing' Mordecai for having such a lean, skinny body in comparison to his tall stature a few weeks ago. It was something that Mordecai had never really thought about, and it wasn't until recently when Rigby had brought it up, and had proceeded to joke about it, that he began to notice it. He would also give Rigby a little punch when ever he joked about it, and acted as if it was nothing, but in reality it had been kept on his mind for quite awhile. It wasn't until when he was walking down an alleyway one evening and saw someone selling 'off-brand' pills and medicines that he thought of trying to change his body. He bought a bottle with simply 2 things labelled on it, “Expand” on the front, and small print on the back with instructions on how to take them. The man had said that the pills would make anyone, well, “expand”. Mordecai had just thought that it would give him a wider, more proportional stature, but he was in for a very big surprise.

He looked himself up and down in the mirror - nothing. He still looked like his usual, skinny self. He sighed, he has disappointed that they didn't work, but then again, he wasn't too surprised because of where he'd bought them. He began to lower himself into his chair, when all of a sudden he heard a strong hissing noise, coming from within him. Mordecai shot up, placing his hands onto his belly and legs. They were expanding, stretching, becoming thicker, fuller, pushing outwards. He looked at himself in the mirror once more, and he saw himself appearing very.... bloated. His long black legs had puffed up, rounding out as they let out a small creak as Mordecai tried to bend them, without success. He mid-section had also rounded out, becoming soft and squishy, like a balloon. It had began stretching all around him, in front of him, behind him, and also to his sides, pushing his arms up slightly as they rested on his bloated gut. His arms continued to rise, but not from being pushed, but from inflating. As they expanded like long balloons used for modelling, they pushed out, forcing them to rise to be sticking out directly in line with his shoulders. He let out a small gulp, this wasn't what he wanted! He quickly began to grow panicked as he tried to bend his arms and legs to walk, but they were forced out straight, letting out small creaks when ever he moved. He grew taut and rubbery as his whole body continued to expand, beginning to round out. Mordecai began to grow unsteady due to his new found size, and he fell onto his front. He bounced lightly as his belly pushed against the floor, adding to the mounting pressure, and he rocked on his blimp of a body as he thought to himself, “There's no way out of this, is there?”

*squeeeeeak*
Mordecai's body continued to expand, as his entire body began to slowly rise into the air. “H-help!” he stuttered out, breathlessly, but all that came out were cute little squeaks. His blue skin grew tighter and tighter as it began to push against the furniture of the room, pushing them away. His cute small feathered tail stuck out of his blimp of a body, slowly beginning to become absorbed into his overly bloated body. His body let out a longer creaking noise as it rounded out, pushing against the walls, ceiling, and floor of the room. The pressure mounted as Mordecai's small head began to sweat, nervously awaiting his inevitable fate. He no longer looked like a blue jay, he looked more like just one huge blue party balloon, a party balloon that was running out of space. “I-I should've j-just i-ignored Rigby...” He muttered to himself, but it was too late.

He scrunched up his face, in preparation as for what was to come. The pressure mounted and maxed out, his skin as tight as a drum. The hissing began to fade due to the loudness of the creaks and squeaks his body was making. Mordecai let out one last gulp and... BANG!
