New Characters Unkylosaur & Unkonodon! Interactive Experience Highlights 🦕
Rally at the Unko Volcano! Crowd-Participation Battle Against Giant Creatures
Meet the two brand-new characters stealing the spotlight this summer! 💥
Unkylosaur is a gentle giant who loves hanging around bodies of water — but don’t underestimate it! Despite weighing a whopping 1.8 tons, this big softie will launch itself into the air the moment danger arrives 🌊
Unkonodon, on the other hand, travels in herds and uses its distinctive back fin for body temperature regulation!
Small but bursting with creature personality — honestly too cute for words 🥺
The event’s story centers on a mysterious Giant Creature that has awakened due to extreme summer heat — and it’s up to visitors to gather poop power and fight back! ⚡
Inside the venue, you’ll be channeling that poop power into the Unko Volcano as part of a crowd-participation experience — the kind where the whole audience feels like one unstoppable team 🌋
