Blowpipe

A blowpipe is a weapon involving some sort of apparatus to blow through and darts. In the Redwall series, blowpipes were often used in conjunction with poison of some sort. In two instances, a deviation of a blowpipe was used. These were:

Janglur Swifteye when using his flute as a blowpipe

and

The sons of Wirga, who used a spear convertible to a blowpipe.
