The Spectre Number Zero is a Special Mission that occurs in Cloud Graffiti. It consists of a 4/4 Spectre Number Zero (a Spectre but completely black) being attacked by multiple I.G.B.Ms. The Spectre Number Zero does 25x more damage to it. The Spectre Number Zero also has a very rare type of Bloontonium (which needs very air friction to work) that makes the I.G.B.M deal 4 HP to it. $4000 starting cash. Medium difficulty. $250 cash round.
Description: The Apopalypse Bloon is very mad becuase the Monkey Aces can fly and he thought the Bloons were the only ones that could do it! Our best Monkey Engineers and Bloontonium Reasearchers have built the Spectre Number Zero to counter-attack all those I.G.B.M attacks!
