Montral/Legends

"I'm sure you've noticed the conical protrusions on General Ti's head. Many think they are horns, but they are actually sensory cones that detect vibrations, almost like a ranged sense of touch. And, like any sense, it can feel pain."

- Grievous, to Aayla Secura on Shaak Ti

Montrals were conical, horn-like protrusions growing from the heads of the Togruta species. These sensory cones could detect vibrations like a ranged sense of touch. They were used for echolocation.

Description
"Give in, Ahsoka... Give in to the pleasure...and I'll make you cum so hard again you can fly away on your pretty little montrals!"

- Asajj Ventress, to Ahsoka Tano

Montrals were a major erogenous zone. Oral sex could be performed on a montral. The Jedi Archives in the Jedi Temple on Coruscant contained the holobook Perfect Montrals.

Behind the scenes
Some stories, such as "Jedi Requirements" by Kal Orin, mistake montrals for a Togruta's head-tails.
