List of failed NES spin-offs

This is a list of NES spin-offs on ESB that did not become as popular as the original. None of them are canon, but NEM and its related Never-Ending Snail Story are. Meanwhile, some of the noncanon spin-offs, like Chapter 0, had many messages like a normal part, although along with NEM, Chapter 0's second part failed.

Failed Spin-Offs
1. Chapter A-Created by 100.35.58.135B, this prequel part only had one message about SpongeBob and Patrick, and did not take off.

2.  Never Ending Story But It's Opposite Day-This was another spin-off created by Walkingbird, apparently as the exact opposite of NES. It only introduced one character, a cup of tea.

3. Never-Ending Code Story-A part created by Mind Luxor, it would have utilized special codes to tell the story.

4. Never Ending Story: The Great Cave of Secrets-Made by WalkingBird, SpongeBob finds a stone dome, and gets curious, so he goes in, however, the ceiling breaks! He retreats in a hole, leading him in a cave, the rubble covers the entrance, so there is NO turning back. Spongy Spongy, Patrick, Mr. Krabs, and a dude named Shawn also appear.
