Role in series
After having watched a horror film called Night of the Robot the preceding night, SpongeBob becomes increasingly anxious over time and cannot get his mind off the movie. While at work, he starts to hallucinate numerous surroundings in the kitchen to be robots, one of which is a bag of Sea Potatoes with a water bucket on top, next to a broom and dustpan.
SpongeBob uses them to cook kelp fries. They are also called "Sea Taters" in this episode rather than "Sea Potatoes."
- Despite the food's name suggesting them to be made of it, these potatoes are used to cook kelp fries instead of kelp.
