"If Dark Water is flooding into the caverns then there is only one way to stop it, I just hope that you are ready, Eli," said Will.
"What is it?" asked Eli.
"You have to go to the surface and find the Surface Slug," said Will, which surprised everyone all over again.
"There's a slug on the surface too?" asked Trixie.
"It's a secret Slug that can only be found up there, and there is also only one of them which the Shanes have been guarding since the first of us went down to Slugterra," said Will.
"In fact, it was the Surface Slug that allowed us to go to Slugterra in the first place," he said.
"But how are we going to find one slug in such a big place?" asked Pronto.
"You know where the Surface Slug is, Eli, and only you," said Will before the video ended.
"Do you have any idea what he meant?" asked Kord.
"Only one thing comes to mind," said Eli as he thought it over.
"Then head for the surface right away, we'll do what we can here to keep everyone safe till you get back," said Trixie.
"Make sure you all stay safe," said Eli as he put a hand to her left cheek.
"You too," said Trixie. She then gave him a kiss before he headed out for the drop area from the surface.
"So, what should we do now?" asked Pronto.
"We do whatever we can to save people," said Kord at the same time Trixie went and uploaded their message. Meanwhile, Tad and the others were standing at a safe place in Rocklock Cavern.
"That's one cavern down," said Dr. Blakk while watching the Dark Water submerge everything in sight.
"Yeah, but knowing Eli he's going to try something to stop us," said Tad.
"There's nothing that the human can do to stop us now that so much Dark Water has filled this cavern," said a Darkbane.
"Actually, there is a way according to his father's memories," said the Goon as it turned to look at Will.
"I knew this was too easy," said an angered Tad.
