The Mollusking Family is a family in Pikmin 2 for the Nintendo GameCube. I have no idea what they are based on. The two enemies are Ranging Bloyster, and Toady Bloyster. You can kill these by attacking the bulb on their backs. The ranging Bloyster is a boss while the toady bloyster isn't. you can also throw Purple Pikmin on their purple and pinkish bodies to hurt them. Their habit is eating Pikmin.

Ranging Bloyster is a boss in Pikmin 2 only. This boss is different, it tracks only your active captain. You have attack the bulb, or start chucking Pikmin at its pinkish-purpleish spot. It is way easier with two captains.

Toady Bloysters are enemies in Pikmin 2 and Pikmin 3. There is only one of this monster in Pikmin 2, at Perplexing Pool. However it comes back every day. You can kill this by throwing Pikmin on its bulb, or by throwing Purple Pikmin on the purple spot.

In Pikmin 3, they appear a bit more often, in Garden of Hope and Twilight River. They also spray ink this time, instead of shaking the Pikmin off.
