The Marine Tube

It was quiet. Only the sound of footsteps echoed the tunnel as they walked, their Pokemon next to them.

Nate to the left, Rosa to the right, and Hugh behind them - the three friends looked around, amazed at the sight.

There were several Pokemon, if some familiar to them, then many unseen, too. From the group of small Luvdisc to gigantic Wailord. They were countless.

But their eyes widened when they felt the tube wavering beneath their feet. Even with the tube closed, they could feel the pressure building outside.

They witnessed a giant passing over their head: Legendary Kyogre.
