Rockjaw and the Wilders have challenged the Heroes of Goo Jit Zu to a Goo-lympiad! It's a multi-event challenge tournament where they have to stretch their goo to the limit... but if the Wilders win, the Heroes will lose their power. It all comes down to an epic race - can Thrash win it for the Heroes in his Thrashmobile?!
Thrash is venturing into the ocean to find the source of those strange deep sea Goo signals. The ocean in this area seems to have a Goo-ish green glow that enters Thrash’s body and activates his Deep Goo Sea Goo-volution. As he dives deeper, an entire undersea civilization appears in front of him! Temple-like buildings, cobblestone streets, and a magnificent statue of KING HYDRA!
To seek revenge on the Heroes of Goo Jit Zu, Rockjaw embarks on a journey for a treasure chest holding golden weapons that transform him and his new allies into Cursed Goo forms. Meanwhile, Blazagon, Thrash, and Pantaro also become cursed and must race against time to find the Pirate King’s final chest before turning into Wilders. Who will win in this epic battle and reach the ultimate treasure?
Blazagon, Thrash, and Pantaro undergo a new Goo-volution and transform into their Knight forms. When they arrive at a medieval castle, the ground suddenly opens beneath, dropping them into the castle’s courtyard packed with roaring and cheering Wilders. A familiar voice echoes through the arena – it’s Rockjaw, Redback… and who’s the new guy?
