Create-a-Ninja

This is an entry into a Create-a-ninja, run by Z and [link], using a random ninja generator and a vivid imagination.

My slice randomness goes:
This cunning ninja is very short and has a musclular build. His deep set eyes are blood red. He has staight chestnut hair. His outfits include an overlarge pair of boots. His preferred wapons are crushing weapons. He is skilled at painting. He can change his mucus into a variety of useful items.

(a huge paintbrush is a crushing weapon, isn't it? 8))
(and yes that greenish stuff is mucus, he must make a fortune in 'flu season)

Have fun.
