Sonja pops her head out of the tank.

"Is that the robot you're talking about?" asked Sonja.

"Y-Y-Yes." Mettaton wheeled to Sonja which he is astonished of Sonja's looks as a Mermaid.

"My, my...For a human that can transform into a Mermaid when touching water is amazing. This gives me an idea for an event for my TV show and this will involve you, me and your boyfriend too." Sonja's eyes went wide, knowing that Mettaton meant when he said boyfriend. He is talking about Sans!

"W-What Sans? What do you mean that? Why is Sans in this?" asked Sonja.

"You'll see darling. Mettaton out!" He rockets out of the lab.

"Well that was something." Sonja's face is red after Mettaton is talking about Sans and Alphys noticed it.

"So you're in love with Sans, right?" asked Alphys.

"Not technically but I'll see him again." Sonja tries to get out by Alphys stopped her.

"W-Wait! Don't get out! If you stayed in the tank maybe monsters will think that you're a monster too and they'll try to avoid you or c-c-chat with you nicely." Sonja smiles as she ducks down.

"Does this tank have wheels?" asked Sonja.

"Y-Y-Yes and it's equipped with a water proof controller where you'll drive your tank anywhere in the Underground and the water can change temperature too like hot, warm or cold." Alphys explained.

"What's the temperature in the water now?" asked Sonja.

"Warm now but when you get out in the Hotland you might want to be cooled down a little." said Alphys.

"Cool!" said Sonja.

"By the way can I see your phone?" asked Alphys.

"Sure." Sonja takes out her phone which it was shooting electric bolts from being the water.

"O-Oh dear. Your phone's broken! H-Hang on a second." Alphys ran and put some arrangements on the phone. She came back to Sonja which she pops her head out of the water.

"T-There. Your phone now has a keychain, texting and waterproof." Sonja takes the phone, looking at it.

"Thanks!" Alphys lets out a nervous laugh before going silent for a few minutes.

"I have to go the bathroom!" Alphys ran out and closes the door, leaving Sonja confused. Sonja shrugs before driving the tank outside of Alphys' lab.

(I hope you like it and I don't own anything.)
