But what smelly compounds are in these waste products and oils?
The stinkiest compounds are thiols and carboxylic acids, so most likely these contribute to a taun taun's foul odor. Here are just some of the possibilities:
methanethiol....smells like: rotten cabbage
ethanethiol....smells like: burnt rubber
propanethiol....smells like: garlic
butanethiol....smells like: a rotting corpes
hexanethiol....smells like: dead fish
hydrogen sulfide....smells like: rotten eggs
propanoic acid....smells like: used tampons
butanoic acid....smells like: rancid butter
pentanoic acid....smells like: dirty socks
#1 insult: You smell like a Taun Taun!
