The Core of the Sun

The Map
The map is a 2 Entrance Expert track that looks like the layers of the sun, There is no visible water in this map and the black area is unplacable at all. Any fire based attacks on this deals 5x Damage. Damages 1 HP per 3 rounds of every tower, Ice tower is unplacable. At round 100 it spawns in 2 Solarium Bloons on both entrance so good luck

Disadvantage: If any bloon goes into the center/core every tower will be damaged by 3 HP
