As seriously cute as that would be they could be stepping into some sticky legal territory potentially if the devs of the game made this mod.

Cult of the Lamb is a trademarked/copywrited IP. Not sure how litigious Devolver is as a studio with their content either. Just I would be cautious about copywritten stuff and how closely it can be traced to the devs of this game.

Perhaps if it stayed in the workshop it may be fine? Dunno all the ins and outs of that. I would urge the devs though to look into the policies of that before doing anything that could risk a CaD notice or worse a frivolous lawsuit against what is a tiny dev team of furries making a obscure adult game about cockvore.

As far as I know this game is one-of-a-kind. I'd hate to see anything bad happen to it. I hope it inspires more adult fetish games like it.

Still a cute idea though. I think Gruff would look great with the hat and poncho. Poncho likely wouldn't get in the way of the c0ck either I think. Or perhaps make it small enough to where that is not an issue.

I did like the idea of adding the Lamb's outfit to Gruff and put it on my backburner as something to do once all the big bug fixes are done for all of the mods so far, but Yenapaws does raise a good point - it might be a little bit risky. The CotL devs do seem insane enough to not mind such a mod but... I would not want to find out for myself!

Perhaps a legally distinct outfit can be done in future though... Some sort of poncho would look cute, and possibly a crown of some sort

As long as there are clear and very distinct differences I thiiink that is all the defense you need. This coupled by the fact this game is obviously not a global viral sensation. I think by default this will fly well under the radar of Devolver if you play it that way. You are small enough I feel it is a waste of Devolver's time and money to pursue anything if you make a 'inspired' outfit.

Please do consult others more experienced in this though than me.
