Broccoloid

Broccoloids are a species of what appear to be sentient broccoli.

Biology
They have the appearance of anthropomorphic broccoli with strangely monkey-like feet. They also possess pink eyes, and sharp teeth.

History
They were first discovered when they invaded Townsville, and implanted their spores in the town's broccoli supply, that would hypnotize anyone who ingested them. However, the children of Townsville didn't eat their broccoli, so they were unaffected. However, their menace was later defeated when they got eaten themselves, by the Powerpuff Girls, and other children.
