I watched the Chip N' Dale movie a few weeks ago, and with all the nostalgia, I just had to go back and rewatch the series, you know? Then I decided to look around on the internet, and came across something interesting.
It turns out that Frank Angones had a reboot series planned, which would've brought in characters from The Rescuers(specifically Bernard), because the Rangers want to follow in the footsteps of the Rescue Aid Society, leading to a mystery about the society fizzling out after Bianca's disappearance. We'd also have gotten some backstory of the society being founded by Oliva Flaversham from The Great Mouse Detective.
Disney said no to the idea, and after finding out about this, I only have one thing to say:
My disappointment is immeasurable, and my day is ruined.
