Worms W.M.D

For this trophy you need to kill 20 enemy worms using Prod.

The easiest way to unlock this is to set up a local match against 3 human teams of 8, set teleport in to on before starting and place all of the other teams' worms on top of each at the edge of the landscape overlooking the water. Simply prod the bottom worm and most of them should fall in the water.
