BangbooBounce

BangbooBounce arrived with Zenless Zone Zero’s Twitch launch and used Eous, the rabbit-eared Bangboo companion connected to the Proxy siblings’ Phaethon identity. Bangboo are the small robotic helpers found throughout New Eridu, while Eous accompanies the player’s Proxy work inside Hollows.

During launch, viewers were explicitly encouraged to “do the BangbooBounce” in their favourite streamer’s chat while Zenless Zone Zero launch partners appeared on Twitch’s homepage. The bouncing Eous image made repetition part of the joke, and some communities even created chat commands that posted whole rows of BangbooBounce at once.

When this emote was active, viewers typed BangbooBounce in Twitch chat to use it. Viewers used it to celebrate Zenless Zone Zero, react to Eous or other Bangboo, and fill chat with repeated bouncing mascots during excited ZZZ broadcasts.
