I've hatched several grendels with body data that didn't quite work out, so their parts were sort of floating detached from each other. I unfortunately don't have screenshots and the save file is inaccessible due to some sort of memory error, but you just gotta believe me that these were some weird Rayman-lookin' grendels.
Oh yes, I do believe you. Those problems are actually relatively common with grendel sprites, because their proportions are wildly different from those of the other species.
As for my own contributions: I could offer this gem which is a cross of Nano Norn and Banshee Grendel. These cuties actually turned out quite nicely, although the ATT error is kind of hilarious. Not sure how it happened, though, I did have Vampess' ATT fix installed. Two more Vampyre splices, this time involving Micro ettins.
I long, long since don't have a pic of this guy, but I remember playing C1 as a kid and importing a slightly black-tinted male Horse Norn from somewhere. He was a perfectly normal creature except for having adult body data through all his life stages, meaning his body parts weren't even touching each other when he was a baby. I named him Lanky.
