Nematodes are a parasitic worm-like species that eat anything they can find. They first appear in the episode "Home Sweet Pineapple" and are voiced by various actors in the SpongeBob SquarePants cast.

Nematodes are beige-green. They are not often seen but if they are, they will eat something. They seem to be lead by one leading nematode which calls out things like "hungry," "still hungry," or "thirsty" and leads its followers to foods and drinks. They eat just about anything and drink pineapple juice.

Role in series

"Home Sweet Pineapple"

They eat one coral and Fred's boatmobile. Their hunger is still not satisfied, so they consume SpongeBob's pineapple and then leave.

"Opposite Day"

When the realtor talks to Squidward about moving, she says in response that she will considering selling his house as long as it is not infested with nematodes, surrounded by troublesome neighbors, or anything else like that.

"Sailor Mouth"

Nematodes is misspelled as "Nematoads."

SpongeBob reads out one of the dumpster writings outside of the Krusty Krab, "Nematodes are people too." Also, Nematodes is misspelled as "Nematoads."

"Best Day Ever"

They consume the Krusty Krab and thus put Mr. Krabs' business into jeopardy, even leading the restaurant to being condemned. SpongeBob tells them to leave so he can get to work, but they ignore this command and then proceed to eat his pants. However, they are then lured out by SpongeBob once he starts playing the tune to "Best Day Ever," using his nose as a flute.

They fall asleep after SpongeBob takes them out of Bikini Bottom and becomes tired from playing the song.

"Gary's New Toy"

After Gary chose his ball over SpongeBob, the latter decides to move out and live under a bus bench on his own. He sees a nematode and befriends it, but it immediately steals his wallet and crawls off.

Things that they consumed

  • Giant coral with rocks
  • Fred's boat
  • SpongeBob's house
  • The Krusty Krab (they almost did it but they were quarantined)
  • SpongeBob's pants


  • Nematodes are actually roundworms, and are creatures that can live in any environment. The show depicts their behavior more close to the desert locusts in real life, as they come in swarms and consume any vegetation that comes in their path.
  • SpongeBob SquarePants is the second Nicktoon to mention nematodes; the first time was Doug in the episode "Doug Bags a Neematoad." During a camping trip, Roger Klotz tells Doug about the creature and encourages him to catch it in a manner similar to a snipe hunt.
