From publisher blurb:
An alternative way to enjoy The Lazy GM. Maybe you need a monster for a campaign but don't want to buy a large collection. The Lazy GM Single Shots take a single monster and give variant Hit Dice, templates, builds and class levels for both Pathfinder and traditional 3.5 OGL, for a bargain price.
Ankheg features material previously found in The Lazy GM: Dungeon Beasts, but adds a few new builds, including the winged ankheg and the lava beetle.
A fully clickable index cross-referenced by CR and templates, plus bookmarks, means you can easily find just what you need.
