Plankton's lab is a minor live-action character who only appears in the episode "Plankton!" He can been seen on a massive TV in the Chum Bucket.


In the episode "Plankton!," is revealed that Plankton has a pet Labrador Retriever. As he is controlling SpongeBob via mind control, they walk into a room and Plankton says "This is my lab!" rather loudly. In the room, there is a large theater-like screen showing a video of a Labrador above water, barking in a seemingly suburban area.

Plankton's lab also appears in the console version of video game Nicktoons Unite!


  • The end credits of the episode list the dog as "Alex."
  • This is a pun, as when Plankton was taking SpongeBob to his laboratory, he walked in this room and said "This is my lab!," and then he walks over and says "This is my laboratory!"
  • The dog is specially a Labrador Retriever, which is a type of gun dog.
