I'm having some trouble getting stingers on my dread troll's tentacles. Here's the raws
Four stingers
[BODY:4STINGERS]
[BP:RUT1:stinger:STP][CON:tentacle][SMALL]
[REL_SIZE:500]
[BP:RUT2:stinger:STP][CON:tentacle][SMALL]
[REL_SIZE:500]
[BP:LUT1:stinger:STP][CON:tentacle][SMALL]
[REL_SIZE:500]
[BP:LUT2:stinger:STP][CON:tentacle][SMALL]
[REL_SIZE:500]
Body plan
[BODY:HUMANOID:FOUR_TENTACLES:2EYES:2EARS:NOSE:2LUNGS:HEART:ORGANS:HUMANOID_JOINTS:THROAT:NECK:SPINE:SKULL:BRAIN:5FINGERS:5TOES:MOUTH:TONGUE:FACIAL_FEATURES:TEETH:RIBCAGE:2HEAD_HORN:2TUSKS:4STINGERS]
you are saying [CON:tentacle]
CON goes by BP token like how head is HD
CONTYPE goes by types HEAD, STANCE, GRASP, SIGHT, etc
CON_CAT goes by categories
so you might want [CON:RUT][CON:LUT][CON:RLT][CON:LLT]
or just make one stinger that connects to all tentacles
[BODY:TENTACLE_STINGERS]
[BP:TS:stinger:STP][CON_CAT:TENTACLE][SMALL]
[REL_SIZE:500]
above will connect to any bodypart that is categorized as TENTACLE which is in FOUR_TENTACLE
PS that body plan has claws on the Tentcles you could just use a bodygloss to rename the claws to stingers.
EDIT:
also with the category stinger they will show up in the body list as "monster's upper right tentacle's stinger"
