Eggnog

Eggnog (also known as Egghead, or as Life Jacket Kid, Lifevest Kid, Lil N***a, or Lil Ni🅱️🅱️a by fans) is an image of a young black boy wearing a yellow life jacket. This image has become a minor meme on the SiIvaGunner channel.

Origins
According to toonlink, Eggnog originated from a friend of his, DatManOvaDer. A mutual friend had posted a picture of himself at the beach, and much to their amusement, a funny-looking kid in a life jacket also ended up in the photo. The first Eggnog rip, "Maroon Valley - CrossCode", was initially made by DatManOvaDer exclusively for their private server, but toonlink wanted to upload it to SiIvaGunner. DatManOvaDer agreed to it, and then made additional Eggnog rips for the channel.

Rips
Most of the major Eggnog rips were in early-mid 2017, though he has made cameos or been briefly alluded to in a few rips from late 2017 to early 2018, and made a return rip early 2019.

Eggnog's first appearance was in a background joke in the January 2017 rip "A "Hard Day's Work" - Mr Rental: The Video Game". Starting in April of the same year, several rips featured Eggnog as a major character. Most of these rips have the same format: Eggnog appears over a white background as the teleporting sound effect from  plays. He gets closer, and a flashing, mutilated image of a celebrity's face suddenly appears, accompanied with the explosion sound effect from EarthBound. Afterwards, random unrelated jokes play. The exception to this is the "Lucy in the Sky with Dynamites" rip, where he jumps out of the screen from the darkness and vanishes.

In the second batch of rips from mid 2017, Eggnog appears at any point in the video, where he will make an "earrape" noise as the phrase "HOWIE DOIN" appears on screen. From late 2017 to early 2018, Eggnog no longer jumpscares the viewers, and instead makes very brief cameos, typically with his image briefly replacing that of somebody else's.

After a long hiatus, and a brief cameo in "Unusual Circumstances - A SiIvaGunner Christmas Comeback Crisis Side Story", Eggnog rips made a return in 2019 with "Friends Puzzle Time - Kirby Star Allies", a throwback rip to the original early 2017 format.

Trivia

 * According to toonlink, he and Nape Mango are developing a story and game ideas for Eggnog. The project has two playlists on the SiIvaGunner channel, ' and ', and has a SoundCloud account.
 * Eggnog (especially in the mid 2017 rips) is similar to Green de la Bean in that his appearance prompts a surreal jumpscare. However, Eggnog did not receive the same level of hate as the Bean did.
