What does Yoda smell like?

He has to be a mammal right? He's got hair so that's a given. Comparing him to terrestrial animals would conjure maybe monkeys or a large rodent. Its never brought up in the films, but I think Yoda must have had a distinct odor. Of course in the first series only Luke sees him, and since he spends most of his time on Dagobah kissing Yoda's ass so he can become a Jedi, his judgment is doubtful. There is no indication either by spoken word or facial expression that he finds Yoda offensive. Granted the whole swamp probably stank to holy hell and Luke himself is never seen to shower, but Yoda must have been ripe and rank.
In the later series, younger Yoda is only slightly better dressed and groomed. Again, since he is a Jedi Master it is doubtful anyone would walk in and say "Damn Jedi, what is that ungodly stink?", but I have no doubts that even at his most dignified, he biffed like a goat. I cannot imagine that Yoda was invited to many formal gatherings while living in the capitol city of the Galactic Republic, but I would imagine it caused some sleepless nights among personal secretaries who were asked to come up with excuses as to why he was left off various invitational lists.

But what do we compare his smell with? Mammal most certainly, but that still leaves a wide range to choose from. Based on a purely visual and auditory knowledge of Yoda I would have to place him somewhere between a lemur and a hippo. With a combination of matted, filthy hair and a scaly, grime-soaked body he no doubt let off a reek that would be known second only to the light saber as a deadly killing force. Add to that the musty unsettling smell that permeates all of the muppet race.
From his crackling voice it seems obvious that he smoked in excess, so add stale, rank tobacco to the mix. It was not due to his steely gaze that only the staunchest of politicians and well trained Jedi could stand before him and not flinch.

This also brings to mind the smells of some other notable Star Wars characters. The most obvious being Chewbacca, who no doubt stank like a feces encrusted hill billy, Jar Jar Binks, who must have reeked like a dead crocodile stuffed in a Venzelan's used mattress and the Emperor himself, who must have let off an odor like a burnt corpse left in a Milwaukee gas station bathroom for 6 weeks. Darth Vader at least had the decency to keep his repulsive affrond to the nose captured in his suit.

It is no doubt why the Star Wars universe was always in such conflict and turmoil. The repulsive filthy reeking stench of it's inhabitants must have driven them almost insane with disgust.
I'm sorry now I ever even brought up the topic.
