Twinkle of Contagion

The Twinkle of Contagion (nicknamed the Tinkle of Contagion by Gelatin) is a substance that Donut owned and used on himself for the challenge in "Four Goes Too Far". It appears to be a sparkling rainbow liquid substance that can be injected in to a person through a syringe or needle. It appears to be very watery and not very viscous, as it sloshes around quite a bit.

The effect itself is referred to as simply the Twinkle or, as Gaty called it, the Light.

Effects
If one is infected with the substance, they will appear to glow and make sparkling sounds. The infection is spread when one were to look at someone with the said infection. The glow then transfers to that person until they get looked at by someone else.

Trivia

 * Apparently, the infection can only start spreading when the host announces that the challenge begins.
 * Cary Huang in his reaction video to Four Goes Too Far states that the infection may be painful to some contestants while not to others.
 * As from Four Goes Too Far, Donut had The Twinkle of Contagion for an unknown amount of time before.DoughnutsContagionNeedle.png
 * Rather than just emitting a glow, Marker turns pure white when infected.
 * Even if a contestant looks at the Twinkle from space, they will still get infected.
 * The Twinkle of Contagion substance looks similar to the substance that the Puffball Speaker Box emitted when stabbed, but darker.
 * If you inject yourself with the substance first, you’ll never feel any pain even if you normally would. This is evidenced by Donut screaming loudly when he’s reinfected, despite already injecting himself without pain.
