Easiest way to tame. Build a 1 foundation box with just normal door frames. They can't fir through the frames so this is your trap. Use pretty much any flier to fly to swamp(or wherever you find one) pick it up. Bring back to trap(build at your base) drop it in the trap and then tame. It will be safe, can't run(I mean it moves so slow anyway) feed it cakes and badabing badaboom
