Type II Bangboo and Travelboo: A Look Back at Zenless Zone Zero's Messenger Event

In the neon-soaked streets of New Eridu, even the smallest Bangboo can dream of grand adventures. Type II, the cutest and smartest Bangboo friend a Proxy could ask for, once discovered a brand-new Travelboo model and invited everyone to flip through its instruction manual. That invitation led to a limited-time Zenless Zone Zero campaign on Messenger and WhatsApp, an event that ran from June 6 to July 6, 2024. Now, looking back from 2026, it stands as a charming example of how HoYoverse blended in-game rewards with everyday messaging apps.

The premise was simple and playful. Travelboo, a curious little machine with a packed bag, prepared to set off on a journey. Before it left, Proxies had to choose one item to accompany it. That item could change where Travelboo went, turning each trip into a small surprise. Once Travelboo returned home, it would randomly deliver travel snaps, Dennies, Crystallized Plating Agents, or other rewards. Every participant was guaranteed Polychrome ×40. Well, that is the kind of deal that made logging into a chat app feel almost like opening a treasure chest.

Event Duration and Reward Delivery

The original schedule was clear, and it is worth preserving for anyone curious about how the campaign worked:

Phase	Dates
Event participation	2024/06/06 12:00 – 2024/07/06 12:00 (UTC+8)
Prize delivery	After 2024/07/10
Reward redemption deadline	2024/08/14 6:00 (UTC+8)

Because the current year is 2026, those windows have long closed. The redemption codes from this particular event cannot be claimed anymore. Still, the structure remains useful to study, especially for players who wonder how HoYoverse experiments with cross-platform promotions.

Rewards and How They Arrived

Participants who followed the steps received a redemption code. The guaranteed reward was Polychrome ×40. After Travelboo returned, there was also a random chance for additional goodies: travel snaps, Dennies, Crystallized Plating Agents, or other items. The rewards were not delivered directly into the game. Instead, Proxies had to redeem the code in Zenless Zone Zero. This detail mattered because codes expired, and forgetting to redeem meant losing the rewards.

Participation Steps

1. Head to the official Zenless Zone Zero account on Messenger or WhatsApp.

2. Send the word Bangboo into the chat.

3. Choose an item for Travelboo to take on its journey.

4. Subscribe to the official account.

That was it. No complex puzzles, no combat challenges, no timed dungeons. Just a chat, a choice, and a subscription. The event rules stressed that rewards would not be delivered if a player did not remain subscribed during the event. That condition was easy to overlook, and it turned a casual click into a commitment.

Rules That Shaped the Journey

Several rules defined the experience:

• Before departure, Proxies chose one item for Travelboo. The choice could not be changed.

• Each Messenger and WhatsApp account could participate only once.

• Each HoYoverse account could claim rewards only once.

• Multiple Messenger or WhatsApp accounts could be used to see different destinations and collect different travel snaps, but Polychromes and other in-game rewards remained limited to one claim per HoYoverse account.

• Remaining subscribed during the event was mandatory.

• Redemption codes had to be used before the expiry date.

The travel snaps were the whimsical heart of the event. They gave Travelboo a personality, as if the little Bangboo were sending postcards from distant corners of the world. No worries if a Proxy missed one snapshot; the randomness was part of the charm. The official FAQ even refused to reveal Travelboo's travel plans in advance. Surprise, Proxy! That secrecy kept the community guessing and sharing their results.

FAQ Highlights and Practical Notes

For players who needed help, the event FAQ answered common questions. Rewards could be redeemed through the in-game menu: open the top-left menu or press ESC, then go to More > Redemption Code, enter the code, and click Redeem. If someone accidentally unsubscribed and resubscribed after the event, rewards would not be delivered. If a redemption code was forgotten, it would not be resent. And Travelboo's destinations remained hidden until it returned home.

There was also a forward-looking note: the official Messenger and WhatsApp accounts would host exclusive reward events in the future and periodically notify Proxies about version events, community events, live streams, and other news. That promise gave the campaign a second purpose. It was not only about one Travelboo trip; it was about building a direct channel between HoYoverse and its audience.

Looking Back from 2026

As of 2026, the original Type II Travelboo event is a closed chapter. Its dates have passed, its codes have expired, and its rewards can no longer be claimed. Yet the event remains a neat snapshot of Zenless Zone Zero's early live-service era. It showed how a gacha game could step outside its own client and meet players in the apps they already used every day. It also showed that even a small Bangboo could carry a big promotional idea.

For modern Proxies, the practical takeaway is simple: official Messenger and WhatsApp channels may still host new events, but each campaign has its own rules and deadlines. Always check the current dates, stay subscribed if required, and redeem codes before they vanish. Type II would probably nod approvingly at that advice, then waddle off to find another Travelboo model. Some Bangboos just cannot resist a journey.
