This makes me remember a funny line from George Carlin. (since your gulo looks like it just snorted a line of cocaine :) )
"Alright, enough nostalgia, what about some modern forms of capital punishment. How about we throw a guy off the World Trade Center and whoever he lands on wins the Publisher's Clearing House? OK something a little more sophisticated, you dip a guy in brown gravy and lock him in a small room with a wolverine who's high on angel dust. There's one guy's not going to be fucking with to many kids at the bus stop for a while."
How did you find this animal? They are extremely rare, and you not only found it, but you captured it's expression beautifully. I have a soft spot for Wolverines -- as a graduate of the University of Michigan, I am known as a Old Wolverine myself! (The Wolverine is Michigan's mascot, even though there has not been a Wolverine spotted in the state of Michigan for over 100 years.) When I sent to school there back in medieval times (the 1950's), they had a stuffed Wolverine on display in a trophy case. This one is a bit more lively.
