S.O.D.I.U.M. (Bramble's Conception)

The S.O.D.I.U.M. is the second weakest Alkali Blimp, with 450HP. It moves at the speed of 1.5 compared to a Red Bloon, leaving it slightly faster than the Blue Bloon.

The S.O.D.I.U.M. is the first explosive Alkali Blimp. Hitting it with a water-based attack creates a small explosion, dealing 4HP to everything nearby, and sometimes blinding towers with eyes, significantly reducing their accuracy for 10 (or more) rounds. The blindness effect can be reduced by 1 round for every other time the blind tower is healed. However, the S.O.D.I.U.M. takes x16 damage from water-based attacks.

The S.O.D.I.U.M. can also throw a saltshaker at the tower, dealing 1HP damage. Every time a tower is hit by this, the next time that tower gets hit by this attack said tower takes more damage. The saltshaker attack also releases 1 to 4 White Bloons.

The S.O.D.I.U.M. contains 4 L.I.T.H.I.U.M.s, 1 M.O.A.B., and 8 Yellow Bloons.
