Grimace Shake

A supernatural milk shake you can buy from mcdonalds putting it simply.

Symptoms:

Once you have taken a sip or two, within 15 minutes to 2 hours multiple things can happen. Typically linked to brain rot, your body will slowly begin convulsing and having seizures uncontrollably whilst you vomit as it tries to remove the milkshake from your body. As this happens, after you have taken a sip all brain growth begins to stop and disintegrates your brain cells normally linked to the stomach or lungs, causing them to fail and reject the beverage, forcing to involuntarily convulse until it is out of your system or until you die. Typically as you begin to lose your mind, your internal temperature rises, causing you to involuntarily want to take off your clothes and run somewhere to catch some cooling wind, all of course during seizures.

Then and only then, Grimace himself take advantage of your mortality and turn you into a vassal for him to terrorize the world beyond his grave in a tradition celebrating his birthday.

Methamphetamine made my shaking a bottle, but a little too heavy with the lithium.
