Road Spike Bloon

The Road Spike Bloon is a bloon that is immune to Road Spikes, and when it passes a road spike pile, it will destroy the ENTIRE pile, however with spikeballs, it will only get rid of one spike. It takes 100 damage to pop. Once popped, it will spawn 3 lead bloons. They cannot pass through to the end of the map, where you would lose health. But right before it reaches the end of the map, it will pop by itself.

Strategies
Road Spike Bloons usually appear on early rounds, where you have weaker upgrades. It is best to get a apprentice with a lightning upgrade to get this guy, and a Dart Monkey combo can also work.

In further rounds, they appear less, as you probably have better upgrades by then.

Camo and Regenerating Road Spike Bloons can be harder to defeat, so a apprentice, that is upgraded, can take care of those.
