you can get the gold key card in the scrub-e game at boo manor,
but it's a couples game so make sure you have hamtaro too.

after the two by the elevator help you get hamtaro out of that steel cage thing, they'll
be back at the elevator.
talk to the one pushing the elevator, he'll say they need
a care key, and the bigger one will say he's right.
then they'll leave and you can use the gold key to get
in the elevator :]

excellent answer

It's physically impossible to finish the scrub-e contest without thius hint. There are
three ghosts floating down toward the ground. Before they hit the ground, go toward the
boxes beneath them and say 'pushie'. the boxs will go up, collide with the ghosts, and
they start from the beginning again. If you have time between pushing the boxs, THAT is
when you scrub-e. You have to keep pushing the boxs up throughout the game.

Those r all good answers ~Mimi
