[I was asked to recreate the Scooby Doo 2 scene where Shaggy and Scooby Doo try the elixirs in the fridge and I ended up doing it as if the scene was Velma Dinkley trying them instead and her body morphs in crazy ways! I hope you like what I came up with.]

In a lab of potions and elixirs, Velma strolled,
Vials and boxes, mysteries to unfold.
Blue liquids beckoning, a tempting array,
A body morphing adventure in a playful display.

First, she sips the potion of brawn,
Muscles bulging, a body reborn.
A bodybuilder's might, strength untold,
Velma flexes, confidence bold.

Then comes a potion, a comical twist,
Inflating her form, oh what a bliss!
Incredibly round, a comical sight,
Velma chuckles, her laughter takes flight.

Next, she sips a potion so sly,
Transforming her shape, she can't deny.
Incredible curves, an Instagram delight,
Velma struts her stuff, feeling just right.

Last in the line, a potion unique,
Super-stretchiness, making her physique.
Limbs extending in incredible ways,
Velma grins, enjoying the maze.

With a wink and a glance, she turns to you,
"Steal this potion, let's see what we can do."
Whispers of copying formulas in the air,
A mischievous plan, a duo's affair.
