The Orange Bloon is an evolution to the thermal line of the bloon army. It is resistant to all things related to heat, and/or fire. Upgrades such as Ring of Fire, Dragon's Breath, and Burny Stuff. It is the size of a yellow bloon though, and also now comes out of a rainbow bloon. (Rainbow Bloons now split into 2 Zebras, 2 Oranges). Refrain for using fire based attackers in the front.
