Garboid: the first of these monsters was spawned accidentally in a trash heap contaminated by undead blood and tissue. They eat literally anything, and are happiest burrowing through garbage and compost. Their internal gases make them just slightly lighter than air, but they travel faster by dropping to the ground and slithering on their own filthy, oily secretions. Their bite transmits a potent cocktail of infectious bacteria.
Blobotle: a human fused with a common flesh-fly. They lack wings but are strong leapers, and their mouthparts drip a highly concentrated digestive enzyme. Though their main diet is dung and carrion, they are hopelessly addicted to raw sugar and will pour it over their usual food whenever possible.
Cackle: these ghostly, floating monsters are known for their devilish sense of humor and delight in cruel pranks, especially if physical injury is involved. They are fashioned with fresh-carved pumpkins, which convert to a tough, bony flesh during the animation process.
Sinister: the most common of winged monsters, these giant, flesh-eating bats are quite popular but difficult to keep under control. They love to cause trouble, even for their friends and masters, and especially like to ruin machinery. Though physically frail, their sophisticated natural sonar makes them deadly enemies.
Sleez: greedy, hyperactive canines similar to the measle in their knack for stealing and obsession with collecting. They spend every moment of conciousness hopping up and down, yipping in their devilish, oddly metallic voices. Favorite trinkets are stored in their own stomachs.
Zombie in a chicken suit: needs no explanation.
