Twitch writes in its official announcement that this is a desire to appreciate the K-pop community, but in fact it seems to be a promotion of a special event that will take place on October 26:
“K-pop will play a remarkable role in the community with a unique show starting October 26, featuring AOMG, Hello82, Everglow and more.”
Whether you’re a K-pop fan or not, everyone is seeing the new emotes in the morning.
How do I unlock these emotes?
Twitch has created a total of 10 emotes that can be unlocked from October 19-30.
“Collect each one by cheering a minimum of 300 Bits, purchasing a subscription, or gift subscriptions on any Affiliate or Partner channel.”
All emotes thus unlocked will be available in your account forever.
