Monster Rancher 3
After selecting the type of training (for example, trampoline
in Morx Forest), rapidly press X to skip the animations for
the drill. It does nothing to the success or failure of the monster.
When Kai challenges you to the battle where you fight the Joker,
have a monster with the Fast Footwork ability (such as a Hare or
someone who just happens to have it). If you manage to get a few
hits off and remain unscratched, it still counts as winning. You
can now train Jokers. Save the game before you attempt this, so
if you lose the fight your monster will not be cut down to only
half life and you can repeat as long as desired.
