Nematodes are any of a phylum (Nematoda or Nemata) of elongated cylindrical worms parasitic in animals or plants or free-living in soil or water —also called roundworms. They are led by one leader Nematode that tells them what to do. They eat everything in their path. Nematodes are only seen in Home Sweet Pineapple and The Best Day Ever.
 Things They Ate
They look like worms but stand on their tails. Nematodes have no eyes or nose but they only have a mouth. And they have rings running down their bodies.
