I just thought I'd put this here to see what you think of the idea.
A few years ago I made a video on YouTube called Lost Adventures of the Blue Cow, which is a parody of the Blue Cow Story segment of the CBeebies show Story Makers.

It's the second-most watched video on my channel and I've been getting requests for a sequel.
One of the ideas I've been playing with on my long walks to work is a cow based parody of Mighty Morphin' Power Rangers, which I've called Meaty Mooin' Cow-er Rangers.
All I have to do is re-colour copies of the Blue Cow into any other colours I need and I've got all the characters I need. Plus a disembodied head who lives in the water cooler. He's their mentor.
