Perfect Storms (2013)

S17E4 SpongeBob SpareParts

After SpongeBob hurts his arm flipping patties, Sandy decides to give him an upgrade. She replaces his injured limb with high-tech robotic parts, turning him into a mechanical fry cook. At first, the new arm makes him faster and more efficient than ever, but the experiment quickly goes haywire. The robot components start taking over, and SpongeBob loses control of his own body, creating chaos in the Krusty Krab kitchen.
