Spiked Bloon

The Spiked Bloon is a bloon appearing in my conception of BTD6. It takes 18 hits too pop, and drops a set of 10 Road Spikes. In order to get this benefit is to pop that outer  layer. It has no children, because of the Road Spikes. It takes the appearence of a bloon bounded in dark, and hardend leather, with large gruesome spikes sticking out of it in random places.
