Bloo's Selfishness was not a particular thing that I liked about Foster's growing up. If he had maintained a kindhearted simpleton image, the five years the show ran would have been (exaggeration intended) the happiest of my life. I never understood how Mac Bloo and the gang had little respect for each other but not enough to stop antagonizing each other. Regardless, you did a decent job expressing Bloo's mixed thoughts and emotions. And about Goodbye to Bloo, I expected a happier ending to the show and it would have made me feel good to have had Foster's as part of half my boyhood. Good job

This is a really nice and sweet idea for a fanfic, but it sounds like you blurted it all out, just like that, without thinking about introduction, body and conclusion. You almost didn't use commas and the paragraphs were sorta random. I agree with you on the idea, though.

Bloo cares about Mac, of course. He /needs/ Mac. In fact, I had an idea for a fanfic about this. No, Mac doesn't die in my fanfic. And it has a happy ending. But it's kinda angsty at one point. You gotta push a character to their limits to really know them, right?

TL;DR: Could be better, but has a lot of feeling!

Aww Bloo really does care for Mac
