R.A.D.O.N.

The R.A.D.O.N. is an unstable blimp with 1800HP. It moves at the speed of 0.3 compared to a red Bloon.

It decays incredibly quickly, losing 1% of its remaining HP every 0.8 seconds. Its decay threshold is higher than normal, being 450HP. It decays into 4 P.O.L.O.N.I.U.M.s, but it has a 3% chance to decay into an A.S.T.A.T.I.N.E. instead.
