Commentator Bloon

The Commentator Bloon is the final boss of Commentary Mode. At the end of that mode, it is revealed to be the one doing the commentary all along. It will give sarcastic commentary while you fight with it as well. It can only be defeated by doing everything that it suggests you should do during this commentary (which may include buying or selling towers, changing targeting styles, placing road spikes, and other random things). This will eventually inflate its ego so much that it will explode, and be destroyed.
