Super Sour Lemonade

The Super Sour Lemonade is a very sour lemonade that when drank, is capable of making a person unable to speak, sing, or make any vocal sounds as it closes their mouth shut.

It was originally utilized by Tibar who originally was going to use it as part of sabotaging Trix's performance, only for him to end up drinking it himself on accident and his mouth to close shut for the rest of the evening at the Battle of the Bands.

Appearance
It is in a container with a lemon sign on top with a nuclear symbol on indicating that it's very dangerous to drink.

Trivia

 * There is a small chance that it actually contains another substance indicating by the toxic biohazard symbol on it, and it's not actually sour, which explains why it closes the drinker's mouth for a while. Sour food and drinks, no matter what level they are, cannot do that feasibly in reality.
