It was the night at the marine laboratory called "The Grey Aqua Squad's Diving Center"
A scuba diver runs away from something that is chasing her. She runs outside from the laboratory, she dives into the water. She hides underwater, knowing that the unknown creature will find her.
As she is hiding underwater, she is being dragged down by the moving algae. Her fate is unknown, the scuba diver is nowhere to be found.
5 days later... Ratchet, Clank, Talwyn, Qwark, Skid, Al and Talwyn's younger 13-year old cousin Mistie head to meet the Grey Aqua Squad at their laboratory.
They received a message from them about a missing scuba diver.
"Can you believe that someone that hides underwater is missing?" said Ratchet.
"Yeah, how can hiding underwater from the mysterious creature help? What if the person drowns, if he or she does hide underwater? said Talwyn.
"So, you're Mistie, right?" said Clank.
"Yes, I am... Talwyn's baby cousin." said Mistie.
"Mistie's shy. She doesn't talk to anyone that much." said Talwyn.
"We understand." said Ratchet.
As they arrived at the Grey Aqua's scuba diving lab, they get off the boat.
"Hello, there. Welcome to the Grey Aqua Squad's diving center, I'm Logan Dallas." said the leader named Logan as he greets them.
"And I'm his sister, Alisha." said Alisha, who is Logan's sister.
"Please to meet you, Alisha." said Qwark as he shakes hands with Alisha, having a crush on her.
"And same to you, Alisha." said Skid, also having a crush on her.
Skid and Qwark glared at each other.
"We heard that there's a missing scuba diver who ran away from something that was after her." said Ratchet.
"Yeah, I sent you an message to you. It's an emergency about our missing scuba diver. She was exploring underwater the other night until she saw something that was chasing her and never came back." said Logan.
"Don't worry, we're here to investigate the clues." said Ratchet.
"Oh, good. Are y'all staying? We got rooms in the laboratory." said Logan.
"Rooms in the lab? Of course, we will." said Talwyn.
"Ratchet?" said Morris, recognizing Ratchet as his old friend.
"Morris?" said Ratchet, also recognizing Morris.
Ratchet and Morris hugged when reunited.
"I didn't know you're a member of the Grey Aqua squad." said Ratchet.
"Yeah, I studied and scuba dive there with others. What are you doing here, dude?" said Morris.
"Well, we're here to investigate, your leader sent me and my friends the message about a missing scuba diver." said Ratchet.
"Oh, Roxie. She's been missing since 5 days after she saw a creature and was last seen. It's good to see you, Ratchet." said Morris.
"You, too, dude." said Ratchet.
Morris leaves to go inside and study.
"Come on in, we gotta show you inside of our lab." said Logan.
Logan and Alisha guides Ratchet and the others inside their scuba diving laboratory.
