A human girl floating in a tank of translucent blue liquid at CORE’s Laboratory lightly tapped the glass. “Hello.” She said as she poked her head out of the liquid. “I am Frisk. I’m 15 years old.” She smiled, resting her arms on the rim of the tank as she smiled. She was wrapped in waterproof white cloth that covered her chest and upper-torso. She wore some waterproof white shorts. “My best friend is Sans the Skeleton, he’s a student of Dr. Alphys and Dr. Gaster.” Frisk explained, smiling.
