tentacles!! he has tentacles sticking up off his shoulders! not them... other things. ;) there's a way to chop the cr2 to change it from a normal joint to a 'curve' joint. i dont know what it is, though. ;) you'd have to compare yours to a curved figure (the animal tails or whatever). most times it is best to try to avoid that 'curve' deal. you could get smoother bending (in more directions) from making smaller tentacle segments and using regular jps. but if you made them very long, then yes, use the curve. and for the jp Xs, you want to squeeze the green and red arms down around the parts as far as you can, to get the largest smooth blend zone possible.
