The unwitting players are travelling through a swampy forest, but unknown to them, it is owned by a vicious swamp tribe. They have set up a huge net of hemp above the characters heads. The characters have been stepping on snapping twigs. Every time a twig snaps, the string connected to it also breaks. When enough strings snap, the net falls, dropping huge clouds of poisonous toads upon them. If the players somehow survive the deadly tree-toad poison, the smell of the toad-flesh attracts the swamp’s vicious Trogodons (Alligator-Centaurs).
The Rain of Toads
The unwitting players tromping through the swamp won’t know what hit them.
