Stopped by Glacial Hydras

As Lunara had no way to argue further about the Mantis Leviathan, the party rushed through the water. Jinbe's guidance was key as they spotted two more potential crevices or trenches along the way. But they soon arrived at a trench directly in front of them and Lunara came to a gradual halt.

The Hydra Goddess sniffed and let the water pass calmly through her gills. Faint smiles appeared on her many heads. 'This is the one… It's faint, but I can smell the difference…' 

'Then what about your hydra form?' asked Jack.

'I'll change that after passing another thousand meters. The influence of the hydras isn't that large.'

'Even after so long?'

'That--'

'HALT!'

Telepathic shouts caught Lunara off guard. She had only gone a couple of hundred meters into the trench yet she was already spotted by something. Immediately, Lunara frowned and glared into the abyss.
