I've been looking at so much Dai stuff that I've been recommended some... things: 
what the fuck does crocodine perfume smell like
what the fuck does crocodine perfume smell like
My immediate joke answer is of course "Axe"
Alive alligators and crocodiles have an distinctive odour of muddy swamp, slight fishlike whiff of sophisticated rotten meat which they eat
though I bet Crocodine doesn't eat rotten meat
He's a civilized man, Eric
We've seen him eat one thing and that's an entire keg of beer
so not that civilized, then
I think maybe there'd be a middle note of something fresh breeze, because of the vortex axe
Probably something musky in there for the beast king
Maybe some cedar? I don't know I don't do perfume
that doesn't sound like a terrible combo, though
citrus because he's orange
An honorable combination
probably moss
