There is a movie called "Space Dogs", and it's a terrible movie loosely based on the real story of the two first Russian dogs to return from semi-orbit. There are two awful sequels to this movie featuring aliens and stupid plot-points.
This is besides the point.
One of the female leads has a bit of a tummy, and I love it, so here I am, drawing them with a belly full of the other female lead. :)
You think a tummy in space is heavy? It'd probably swing you around with enough momentum.
