Not sure what could drive Zoe to this.
Maybe she already melted all over one of her toys?
Maybe her team mates were out to puddle her?
Maybe she's just enjoying a day off?
Maybe she's demonstrating proper melting technique?
Any flaws here are why I stick to the written word, but I felt inspired to grab a pencil tonight. The grey and black for her clothes were something I realized halfway I needed to use grey so I could show detail in black. I went back and forth between two darker browns for bubbles in the skin tone.
Enjoy a very goopy Zoe!
Update - Tracing this and trying different things.
