Grinch Takeover

The Grinch takeover was a channel event where the Grinch from Illumination's 2018 animated movie The Grinch took over the SiIvaGunner channel.

Summary
The event was initially foreshadowed during the preceding Christmas 2018 event, where the banner was edited to include a transparent image of the Grinch and Max the Dog from the 2018 The Grinch movie superimposed over the lighthouse. On December 6, the Grinch completely took over the channel and the Twitter account, with the Grinch and Max completely replacing the lighthouse and the channel description changed to: "'The Grinch™ has taken over SiIvaGunner! See Illumination™’s THE GRINCH™ in theaters today!'"

The Twitter account's name was changed to "The Grinch", the banner changed to an edit of the Grinch in a  Christmas landscape, the location was changed to "Mount Crumpit", and the account posted Tweets in-character as the Grinch.

Starting on December 19, after the release of "The Grand Finale - Super Smash Bros. UItimate", channel uploads were put on hiatus. Lore-wise, this hiatus went unexplained until Christmas Day, when a comic posted by the @GiIvaSunner Twitter account explained that the hiatus was caused by the Grinch, who grew envious over the Christmas spirit he saw on display and decided to cancel Christmas by putting a stop to rips for the year. Planted in the comic were details for upcoming events: the first mention of the upcoming King for Another Day Tournament, the date of the MAGFest 2019 SiIvaGunner panel and Q&A, and the names of several upcoming or planned rips.

The real reason for the channel's hiatus is because of a series of copyright strikes caused by attempted counter-claims against various rips. These strikes eventually led to the SiIvaGunner Termination.

At the beginning of January 2, 2019, the YouTube channel remained unchanged, but the Grinch seemingly released his grasp on the Twitter account, with the avatar, display name, header, description, and Tweets all changed to be in-character for Wood Man, and the location changed to Maryland, referring to their upcoming MAGFest appearance.

On January 4, the SiIvaGunner channel was terminated by YouTube due to copyright strikes. On February 28, the channel returned with the Grinch's avatar, banner, and description still intact, but they were all quickly and unceremoniously changed to normal. It is as of yet unknown if The Grinch will tie into a canon in-universe explanation for the channel's termination (or if there will be one at all, as done previously).

Rips uploaded
Most of the rips from this takeover were either related Christmas and winter, or related to , referencing the "Grinch Leak". The catchphrase was changed to "Please read the channel description, sponsored by Illumination™'s The Grinch™, in theaters now!"

Two years later, these rips, along with rips from Christmas 2019, were compiled into the album Dr. Pavel's How the Grinch Took Over SiIvaGunner.
