The notion of a landshark either doesn’t work for you at all, or it really, really works for you. If you’re in the latter camp, the bulette is likely already your favorite monster.
The dwarves of Amberhold will not crown their new thane until his family crest is carved on a shield made from a bulette. Since Hemmut Oakenheart is a wizard with a lame foot, he needs surrogates to help him slay one of the beasts—and survive the journey back through goblin and behir-infested lands.
The peasants of Velustan act more like sailors on a grassy sea than farmers, penning their animals on small stony hummocks of land and tending their crops from sail-driven wheeled skiffs. The analogy is an apt one, as Velustan is infested with bulettes, who leap sharp-like upon any prey unwise enough to travel on foot.
Halfling farmsteads ransacked. Burrows collapsed. Whole families missing. Despite the prayers of the priests, the rune-carved boundary wards of the druids, and the mountains that border the land on two sides, the worst has finally happened: Bulettes have discovered the Seven Shires.
