Teardrop appears to be a blue drop of lacrimal fluid, the fluid produced when eyes water, cleaning pathogens. Her outline is cyan, and her inside is azure, which gets lighter towards the center. When Teardrop is at her evaporation stage, she is a very light azure, which is hardly seen.

Has black wirey-stick looking limbs and black circles for hands
She has black dotted cartoon eyes and a black outlined mouth
Cares for her parent-figure
