Moldstool

The Moldstool is a Boss Enemy appearing in Pikmin: Other Frontier. It is a close relative to the Puffstool even sharing the same body structure, but while Puffstools have smooth red caps Moldstools have warty green caps.

One is the boss of the final sub level of Spoiled Mound, however it is more similar to the Giant Breadbug as it dosnt attack directly, it's a passive creature meaning that it will only attack when it is threatened. When it is threatened however it releases a cloud of Mold that converts Pikmin into Moldmin, as such Cleaner Pikmin are the best option when taking on these creatures.

The Moldstool when at half health will begin to run away from you while periodically spraying Mold without the need to be attacked making it quite harder in conjunction with the floor also having Fire Geysers and Olive Bulblings.

Olimar's Notes
"The Moldstool seems to share most of the same anatomy and DNA as the Puffstool I discovered on by first trip to this planet. However this specimen seems to spread a type of Mold that can cause neural problem when inhaled. Due to the lack of any Puffstools in this trip I theorize that the Moldstool is an evolution of the Puffstool."
