I used to spend a bunch of time trying to get the ivory versions of trip trop and truckle.
I used to spend a bunch of time in areas refreshing constantly to try and get them. I never did get an ivory truckle, but I did manage to get three trip trops. I tried to get more but didn’t manage to get any more than that.
Side note: Not sure how I feel about them renaming it to rimehoof. I’m not sure younger me would have hunted them that much if they were, since ivory trip trop makes it sound rarer tbh
