These were fun to make, there's a user on Discord that likes pictures of characters holding their breath, so I quickly used a cube, tons of subdivision and the inflate brush to make these. I got a little practice using a UV mapping trick on the red cheeks version, too. It's kinda dumb, but it was a fun 30 seconds.

I wasn't going to upload these anywhere, but eh, I was bored waiting on an unrelated render to finish.
Just for laughs, here's a download link: https://mega.nz/#!TD5DmRrT!JpIwpxJpI3N_nqKfCRLAf4E0U31ZBjt6tPc3mkjTysI
