Orange Bloon (Zathus' Conception)

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.

It was created when a squadron of yellow bloons were sent to work at the Geothermal Thermite Plant, the heat made them orange, and do not suffer from flames do to their experiences at work. Please include an image if possible.
