Would love to, but unfortunately, I don't think anyone would care enough about the mod for it to be even profitable in happiness. :\ And plus, the mod requires a Minecraft version pushed so far back, I don't even think it's possible to grab the actual source code back from the depths of that pit itself. If I could, I probably would. I'm sorry. :\
Would it be possible to just try and remake the mobs using similar or the same models?
EDIT: thanks for the response btw
Well, I'm not going to bother trying to recycle the model code from that mod, since that MC version is long outdated. If you really wanted to, you could, but it would be a ton of work to do.
And, you're welcome.
