To the lv 64 guy with the alpha raptor:

put 25 stone in your most useless tame's inventory.

If you have a flyer, use it to grab said tame with the stone.

(If not, hope for the best)

Shoot the raptor once to get its attention.

Hop on the flyer, grab the game, and leave with the raptor following you.

At a good distance drop the game and let the raptor attack it.

The stone is left behind in a satchel which the raptor cannot destroy but will attack forever.
