I’m the guy who said if I got 100 ups in tuso I would do mosa so I am

1 locate a mosa. I found many on deep sea near herb island

2 knock it out by letting it fallow you until it imagoes then shot with toxant arrow repeat

3 feed prime meat or kibble I tamed one fine with prime meat and soothing balm

Hope this helps if I get 100 likes again I will do one on giga
