How to tame a yutyrannus with 100% effectiveness.

Step 1: combine 200 oil, 350 cementing paste, and 125 keratin in an industrial cooker. Heat for five hours.

Step 2: tame a rex and at least 25 dodos. Level doesn't matter.

Step 3: once cooker is finished, remove resulting tar and use a brush to apply three even layers of tar to the rex. Avoid the face, arms, and feet.

Step 4: throw dodos at the rex, making an effort to evenly space them on the sticky tar.

Step 5: steer clear as rex has a nervous breakdown ripping the dodos off, leaving the feathers behind.

Step 6: seek shelter as nervous breakdown continues as rex develops the ability to scream and send other animals running.

Step 7: after rex has calmed down, give it a hug. This will bolster its confidence and teach it to support your other "special" tames.

Step 8: rename your rex "fluffers" or "danger floof."

Step 9: enjoy your new yutyrannus.
