What is the least popular program on Nickelodean?

As of my last knowledge update in October 2023, specific viewership statistics for Nickelodeon shows are not publicly available, making it difficult to determine the least popular program definitively. However, shows that receive less promotion or have shorter runs, like "The Loud House" spin-offs or lesser-known animated series, might be considered less popular compared to iconic hits like "SpongeBob SquarePants" or "Dora the Explorer." Viewer preferences can also vary widely, so perceptions of popularity may differ among different audiences.
