With spinoffs, especially when they're episodes in the same show, it can be a bit risky. However I felt that this one paid off.
The Good Stuff:
-The fourth wall jokes are amazing, especially the credits at the end.
-MM&BB are so established that an original episode fit right in. I wasn't annoyed that SB was barely in it like I might be several years ago; instead, I enjoyed the twist, especially because the previous episode put me in the mood. I almost forgot about Spongebob at points, but the brief cuts to Spongebob and Patrick were a good idea.
-The ending was smoothly done, yet hilarious and unexpected. I was expecting a Scooby Doo reference that never came for some reason.
-The references to real superheroes were entertaining, but they never felt out of place.
The Bad Stuff:

1. Why in Back to the Past does Adam West voice young Mermaid Man but in this he doesn't? They're partner episodes! It seems lazy.
Yeah, that messed me up too. What was the point of that? Considering the episodes were a pair it would have made more sense.
The plot could have had more action, but it wasn't so bland that I was bored.
I actually probably liked this better than Back to the Past. Very creative, funny, and different. 9/10
