This one is a more vague suggestion. It can be based on any existing truck (like the Paganotta E35 for example) or added as a whole new model, but the main inspiration is the truck you use in the Septic Avenger sidemissions from Saints Row 2 (a game I’ve been having loads of fun with on my 360)
So why is it in Special? Well… you can spray shit at vehicles around you (literally), making them unable to see where they’re going for a few seconds! The tank slowly refills by itself when not used, but a special powerup can instantly refill it (like tank reload). A fun addition to beginner derby, same levels of toilet humour as the porta potty but much more useful
