An Underwater Cave
They continue their journey untill Ronan notices a cave when staring in the water and they decide to explore it.
Ronan goes first and sends in the Gem of Brightness as a light to see what is inside. He sees a treasure chest but not much more so he goes in and gets jumped by an octopus that was hiding on the cealing of the cave.
Phinux and William come to help Ronan but aren't of much help as the octopus sprays a cloud of inc and they can't see him anymore. The octopus swims away using the cloud of inc as cover and they decide to just let him be. They check the chest but it turns out to just be filled with rocks.
