Phoebe forming herself into a cube, bottom half first!
Phoebe might be a solid, and therefore unable to merge herself together or split herself apart, form holes in herself or fuse seams together, but she has plenty of stretch to take some unconventional shapes! For example - a cube! It takes a fair amount of precision to hold herself in a specific shape, but she's had a lot of practice! It's also essentially omega-level yoga, and she finds it quite soothing. : )
Just a quick color of that sketch of Phoebe cubing herself! I made some mistakes with this one, but I figured I'd share it because I liked how it turned out anyway!
