Rust Bulbling

Rust Bulblings are a species of Grub-dog debuting in Pikmin: Other Frontier, they have dark orange hides an light gray heads with red irises. They also usually stay in small groups alongside other species of Bulbling and Dwarf Bulborbs.

As a larva they were fed a diet of metallic compounds which began to naturally form over thier bodies forming a iron shell, this makes then immune to direct physical harm via throwing Pikmin which allowed for their relatives to be killed instantly, instead they need to be swarmed in order to properly dispatch them. Otherwise Rust Bulblings are similar to their regular counterparts aside from having slightly more health than their relatives.
