Robo Titan

The Robo Titan is a bulky robot built by the Z Syndicate. It pretty much looks like a larger, stronger version of the Z-bot but with a comparatively tiny head. It sometimes launches mortar bombs from its chest but prefers to crush your Pikmin with its massive fists. To defeat it, throw Pikmin at its head until it topples over, then you can swarm it until it deactivates.
