The Sproggans are a Goblin race with a difference. On the face of it, they appear, small, weak and vulnerable, easy pickings for footpads or anybody else who would want to hurt them. Their eyes, which can be green, brown, or yellow, are bulbous and can take in every little bit of light to be found even in a dark area. Their feet are large compared to the rest of their body, and webbed, and suit their swampy homes perfectly. In cities and other built-up areas they wear strong shoes. As those who have bothered them would testify, they have a secret weapon.
If they feel seriously threatened or greatly angered, they can and will inflate their bodies to several times their normal size. Gills on the outside of their bodies and limbs breath in, filling internal air sacs, so that what appear to be weak limbs now bulge with muscles, and what was a four foot Goblin is now the size of an eight foot tall Orc and seemingly as strong. Their voices match their new bodies, and clubs, hammers and other blunt objects will bounce off leaving only bruises. Many would-be attackers have been scared out of their wits by these seemingly formidable Sproggans, and have turned and ran, after which the Sproggans deflate back to their normal size.
What the Sproggans don’t want other races to know, is that their formidable appearence is not matched in reality, but is a case of them literally "puffing up" their bodies to appear very dangerous indeed when in fact they are relatively weak.
And whilst blunt objects will bounce off them and only hurt them slightly, swords and other sharp objects can slash the air sacs and cause the area hit not only to bleed but to deflate to it’s previous size. Therefore,unless enraged beyound reason, they will tend not to pursue a fleeing person very far. Their whole plan in a threatening situation is to intimidate their foes and make them back down without a fight.
Their ancestreal lands are in the Purvis Swamp which has remained theirs partly because few members of other races would want such a place, and partly because they know how to lure would be attackers into the most marshy areas and get them helplessly bogged down. They on the other hand, with their light bones, air sacs and big webbed feet, can walk on top of the surface of even quicksand without getting stuck.
