im climbing the walls about the scuttle monster twinsquish i must know everything. why so many extra hand. why missing one from the "total" feet. why that one leg got a s'many hands on it in particular. is any remnant of remus's consciousness a little bit "okay but the design does kinda slap tho." can i kiss him
The many hands is symbolic of that fact that Remus and Roman are both Creativities, and thus is the appendage they use most.
The lack of the correct number of legs is the same as the lack of correct arms, hands and eyes, this fusion is an abomination. The twins cannot be cleanly made into a single being as they are too wildly different from each other, they are each their own individual and trying to erase that is going to get nasty.
Remus does not actively enjoy being forcefully re-united but he would ask once it's all fixed if anyone thought to take a photo.
And yeah sure you can kiss it if you want, mind the flailing limbs and weapons though.
EDIT: Additionally I've nicknamed the fusion "Createrato" whilst I was working on it, a combination of the words Creativity and Terato.
