Here's my ideas:
-(Special) Mini Wailer: Like the Killer Wail but it would be a small tripod you set up, it would then do short wail-blasts in 4 directions (not all at once, one per, do it four times then disappear) be a whole lot smaller and less range but would be like shot-gun level blasts. Less distance but more radius.
-(Subweapon) "Skrubball": A ball (size slightly smaller than a volleyball) that is completely covered in a scrub-like fabric. you throw it and it bounces 2-4 times then poofs away. If you hit the button quick it's less powerful and won't go far or bounce, longer you hold it the more power and bounce it has. The special property is it doesn't come out with a load of ink, but if it bounces in Your ink it picks it up and grows in size (if it hits enemy ink all that happens is it leaves a blot of your ink).
-(Special) Bubbrella: An alternate to the bubbler, it sprouts out a stick from your tank and creates a forcefield-like umbrella over you. special deal, if you get near your opponent it will grow in size, in a way making you a walking cover.
-(Main weapon) The Krak-on Ruffer: A weapon in the brush class that resembles a floor buffer, like the gatling gun but ground based, it brushes the ground in a circular motion and if charge it (can only charge in place) it spins more rapidly, flinging a bit of ink around which won't cover but do damage to opponents. Attacking with it does a forward fling.
