Sharp Shurikens (BTDB2)

Sharp Shurikens is the 2nd upgrade of Path 1 for the Ninja Monkey in Bloons TD Battles 2. It is similar to its BTD6 counterpart except costs less.

It costs $300.

Summary
Extra pierce for shurikens makes a decent difference to performance of shuriken's grouped-popping. It pairs well with Seeking Shuriken. However, there are no special crosspathing benefits with this upgrade.
