This track is a Advanced Track. It looks like the Voya Nui Volcano. If you put a tower on the side of the volacno, Umbra will come out and destroy it. However, if you put Axonn or Brutaka there, Umbra will be added to your Special Agents. If you have 6 Toa Towers on the 4th Path, they will go inside, and you will get $50000. This can only be done ONCE.
Path[]
The bloons come out of the volcano and spiral around the volcano, loosely.
Piraka Bloons will take a straight path into doorway in the volcano. If they get in, you will not be able to get the $50000.
Umbra[]
Umbra has the range of an Ice Tower, and a 4/2 Super Monkey. He can move. Quite quickly. He also only can use one range at a time. The Blue range (Ice Tower range) deals 12 layers and slices at the speed of a 1/0 Ice Tower. His red range (4/2 SM Range) fires as fast as a 0/0 Sniper and deals 5 layers. A gaint Red laser is seen, and it can pop 34 bloons.
Pro[]
Umbra now attacks at the speed of a SM for both. However, he only pops 5 layers for both. (So as to avoid OPNess)
