I had an Idea [img]graemlins/pi_lightbulb.gif[/img]
Using the theme of dwarven/gnome flatulense and minutaur size
A minotaur is basicly a cow walking upright - and cows have four stomachs => 4 times the production of gas. Get the minoyaur drunk and feed it turnips, cabbage or something similarely gas-inducing. When it is nice and bloated - fire it at the enemy and the impact should release the pent up gasses (remeber some open flame to ignite the gasses). The minotaur will wake up from it's stupor surrounded by enemies and with scorched fur - a sure recepie for going beserk and causing maximum havoc.
You will offcourse have to use a bigger catapult than the standard Dwarven Thrower [img]smile.gif[/img]
