My very young fort has recently been visited by a Giant Snail. Since this was clearly a great danger to the fort, I sent out my militia-in-training (3 losers swinging pieces of obsidian on a stick). For the next 3 minutes or so they proceeded to chase after it. By that I mean the SNAIL was actually outrunning them and they only got in occasional hits as they were pursuing it. Also, the snail was apparently capable of jumping to dodge their attacks...

It eventually ended with the snail getting its shell ripped off (so, I guess it became a slug) and then getting kicked in the brain by one of the soldiers. Now I wanna know if its possible to tame one. It would sure make a great tank to distract the invaders and draw the fire...
