A Yelling Rubber Cinderace

Noelle exploring the back alleys of the Team Yell base, otherwise known as Spikemuth and coming across a discarded Marnie banner. Being a good citizen, she thought she would pick it up to throw it away, only to find it strangely drenched in foul smelling rubber.

It seemed impossible, but as they lifted it into the air, goop flooded out of it- positively saturated in it. They found their hands quickly coated in it- and beginning to morph into... Paws? The effect starting to move across their whole body, changing them subtly. The more goop that ended up on them, whether from the still gushing rolled up flag, or the spreading slime now on them. The more their body took on lagamorphic, and pokémon-like qualities.

Her mind was starting to cloud- harsh rubber and spikey clothing was forming atop their usual ones, while beneath their body was warping into that of a cinderace. They wanted more, they wanted to be more- show their appreciation for Marnie, or something- it was getting hard to think or control themselves.

They felt stronger, faster- and expecially with the bits converted to rubber, looking fantastic. They wanted more. They took the flag above their head and wringed it, squeezing out a torrent of gunge directly onto them- obliterating any trace of humanity still clinging on, and converting them inside and out into a Cinderace... Or, not entirely- their body was discoloured, and above the usual cinderace traits, the clothes of a team yell grunt were sealed onto them- and for good reason.

Once the last drops had been squeezed out and merged into them, Cinderace unfurled their flag of Marnie in all its glory- shining like a beacon among her many fans.
