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



It 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-like area.

He is seen in the "Plankton!" segment of the book.

Plankton's lab also appears in the second SpongeBob level in the console version.


  • 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 specifically a Labrador Retriever, which is a type of gun dog.
