Frogs of War — Andrew Harman

Never mind anti-anti-anti missiles or thermonuclear chilled eels, the Ultimate Weapons are Rana Militaria: The Frogs of War. Have your head off as soon as look at you they would. Hidden in a forgotten village of Losa Llamas, they are discovered by the slimy Snydewinder, ex-Lord Chancellor of Rhyngill and a thoroughly bad lot. And after a temporary halt, his world domination plans are back on track.

Little do Firkin and his friends know that, when they attempt to help King Klayth out of a hole, they will fall headfirst into a whirl of time travel, Thaumaturgical Physicists and extremely unpleasant amphibians!
