Bloatbeasts

From publisher blurb:

This installment of Star Log.EM includes: 1,000 words bloatbeasts, a terrifying monster that heralds from the Deizenra, a fleshwarped world in Rogue Genius Games’s Blood Space Campaign Setting. True to their names, these balloon-shaped aberrations have the horrific power to inflate the flesh of whatever they touch, incapacitating victims with their own bodies so they can be rolled away back to the bloatbeast’s den for dinner. In addition to the standard CR 5 bloatbeast, the terrifying CR 10 bloatbeast monarch is also included within. Also included are two new combat feats for players inspired by the bloatbeast’s tactics: Improved Mobility and Springing Bravado.
