Very easy taming:

Step 1 look for scorpions

Step 2 tame

Step 3 mount it

Step 4 look for carno, rex, etc.

Step 5 just attack they dont agro insects (evil laugh)

Step 6 watch as they fall unconcious

Step 7 shove prime meat down their throat

Step 8 wait or roam around the map

Step 9 tap yourself for a job well done in taming

Step 10 become the boss of the whole island (evil laugh)
