Within the kitchen there was a ball of mold. This mold had been feeding on an oddly sweet and sticky substance made by the one and only Mabel Pines. Its green little body ate in a strange way. There was no mouth on this thing, so it ate like a sponge. Its body soaking in the syrup and occasionally shaking as it continued to do so.
This ball of mold grew with every ounce inhaled. That is, until, it could no longer inhale the syrup as there was no more. This was unpleasant to the mold. Though it had no thoughts beyond existing something had now changed in its life from the wall. That change is that it now knew hunger. It wanted to... consume.
So, it began to roll in its glass confinement trying to find a way to reject its prison.
Mabel walked in on this rolling ball, her eyes wide as she began to remember it was there. After being swept up in her brother's small escapade she had forgotten her new... thing. Like a mother had found a child they had misplaced in the store she rushed to the thing apologizing.
"My mold! I forgot about you! You didn't get lonely right?"
Then she took the bottle and began to angle it so the mold would roll into her hands. The mold let her do this without struggling. It couldn't hear her, nor could it understand her, it didn't have many thoughts being just a ball of mold all. Still, there was a type of understanding written in the mold. Something that had evolved within it since leaving the wall. For it, Mabel was a force of nature. One like a storm or rain. Uncontrolled and life-changing. Its strange instinctual existence wanted her hands and it got to her hands. It shook, pleased. Was this pleasure it was learning? The pleasure of a set of warm hands? The mold did not know because mold doesn't have any thoughts or ideas.
"Well, I won't forget you again little guy. Wanna watch me make dinner?"
Mabel smiled at her mold before grabbing a bowl and placing it in there.
"I feel bad for leaving you in a bottle. I'll let you out for a bit."
Into one glass prison and on to another. The mold began to roll once again.
Mabel made a noise, a teasing sound in the back of her throat, before she said, "I'll get you something to eat. You already had Mabel syrup. How bout you try something else made by my Mabel magic?"
The ball continued to roll.
Carefully Mabel dug through the fridge, glass's clinking as she pushed through them until she reached her goal. Once she saw it she smiled. What she pulled out wasn't visible at first, as it was confined within a Tupperware container covered with painted rainbows. She took this container to the bowl, and when she opened it a disturbingly sweet smell wafted out. Within this rainbow encrusted Tupperware container was fudge.
Fudge with unknown and unusual ingredients. Fudge, that was covered in shining pink and blue glitters. Eatable glitters, of course. Mabel wasn't an idiot. She removed a small corner of the fudge and placed it in the bowl.
The mold stopped rolling.
"Well. I hope you can eat it. Uhh, It will probably work out." She shrugged her shoulders then began to look around the kitchen. "I'm thinking spaghetti tonight."
The mold could not consume the fudge. It rolled into the fudge repeatedly. It wanted it. It wanted that fudge.
So, Its body began to part, and it now had a mouth.
It consumed the fudge. And it shook.
