Yu (still don't know his name) finds this and it ends up being Sarah's foot.
(It got cut off by a Gaundi or something I DON'T KNOW)
It actually turns out, that Sarah is some Human/Mimga hybrid.
(Dear god...)
Why does she still have 2 feet then? I don't know, she got it replaced?
Yu eventually finds out that the foot is Sarah's (how he would find out is still unclear to me...)
And that would explain why she goes hulk when she eats the red flower.
CAUSE SHE WAS HALF MIMIGA ALL ALONG!
She dosen't really grow fur or got the Mimiga ears though...
(She's more Human than Mimiga, but still enough of a Mimiga to be affected by the red flowers)
Yeah, this sounds really stupid, I know... just throwing ideas out there I suppose...
