The plot where Mr. Krabs falls in love with a robot controlled by his arch rival Plankton originally came from the short film Rocky and Bullwinkle (2014) where Bullwinkle falls in love with a robot controlled by his arch rival Boris Badanov. In fact Tom Kenny the voice of SpongeBob provided the voice of Bullwinkle in that short film.
When this episode first aired in some areas, a monthly test of the Emergency Alert System interrupted the program on cable networks. This upset some viewers.
