Territorial Breadbug

The Territorial Breadbug is a deceiving breadbug appearing in Pikmin: The After Years and Pikmin: Sinister Incinerator. They appear identical to normal Breadbugs, but instead of dragging immobile objects back to their nests, these creatures actively seek out Pikmin to eat. It is best to treat every Breadbug with caution as it may be a Territorial Breadbug. Because it does not have a nest and does not carry objects, the only way to defeat a Territorial Breadbug is to continually toss Pikmin on top of it to lower its health.
