The Twitch Glitch pet can be earned as a Twitch Drop during the Twitch Rivals Among Us event .
From now until December 18, Twitch and Among Us are holding their own crossover events that players can get as the Among Us pet with the Twitch logo.
Activating this pet is pretty easy, players just need to watch one of the Twitch streamers Among Us Showdown between December 4th and December 18th. Once a Twitch account has watched one of these shows long enough, they can claim the Twitch Drop and link their Twitch account Among Us.
Looks like some people are having trouble linking their Twitch accounts to claim Glitch!

Working with @TwitchRivals to get it fixed ASAP - you'll still be able to claim it afterwards if you've completed the progress for the drop. :)

Twitch Among Us Rivals Event
The Twitch Rivals crossover event can be watched on twitch.tv/twitchrivals and the full program is available at rivals.twitch.tv. Planned events include Among Us Twitch streamers from around the world, including Brazil, Spain, Korea and more.
When claiming the Among Us Twitch Glitch pet on Twitch, players will need to open Among Us and go to the Data page in the game settings. Click on the Twitch logo and a Twitch login page should open in the web browser. Sign in to the Twitch browser and then return to Among Us. If done correctly, Among Us should appear on the "achievement" page.
