Ummm.... I guess they are bent.
You'd either have to take them apart and straighten them out
or do it with the mold later.
There is a putty type of silicone. Two parts.
You knead it together and them you have about 5 minutes to play.
That could work.
All you have to do is putting something oily on them before you push them into the putty.
Shoe Cream, floor wax or the like.
(Disclaimer: I'm talking like I've done it already, but its an unfinished project thats hanging around here in fact)
They would be nice in lobster orange acrylic :D
