here is all the balloon types that i have seen so far and what they do, gray: nothing special and very basic. camouflage: move slightly when shot so the plane units wont be very useful. red: i have not got very far so i dont know to much about them, they move in a sort of zigzag pattern, and i think they act like the camouflage to. blimp: high HP drops a bomb on every one of your turrets. the bosses: even high HP will one hit kill you and your turrets if you dont have armor upgrades
