Grocks are massive, floating creatures with huge gas pockets in their bodies. They can be found in just about every habitat, but especially in forests and swamps, where they spend their days floating and eating and whistling. As they eat more and more, their bodies will continue to grow so that they can float higher and higher. However, their stomachs are quite weak and delicate, which is why a grock will never get too close to sharp objects. Grock splatter is a well-known nuisance to anyone that frequents their habitats.
