The tag implication #44305 robotic_tongue -> segmented_tongue has been rejected.

Reason: The former seems to be defined in part by the latter. So far as I can tell, robotic_tongue is overwhelmingly used to tag artificial, segmented tongues.

EDIT: The tag implication robotic_tongue -> segmented_tongue (forum #336096) has been rejected by @gattonero2001.

A robotic tongue could also be simply any synthetic material regardless of segmenation or solid one-piece construction (Blade Wolf from Metal Gear Rising comes to mind immediately), although I'd argue the tag as it stands should probably follow the same rules as any other extant robotic/mechanical/cybernetic/bionic/prosthetic organ/limb/appendage/anatomical feature tags, if it does not already. Anybody who is more familiar with that end of the tagging system want to chime in?
