To enter secret worlds, you must first move along any wall or floor
(preferably a vertical wall, falling down as a ball). Now while moving,
continuously press the select button on your Game Boy as fast as you
possibly can (I mean, make your arm shake like a sugar rush). Now as
you're continuously pressing the select button as rapidly as you possibly
can while moving along, you should notice shifts in the walls, and even
the occasional accidental hole. If you can enter the hole, then you're in!
But, be forewarned that most places in the game that you try this will
make you end up stuck in a wall, where you'll then have to reset the game.
The "Select Trick" (rapid pressing of the select button) works best if you
are falling straight down as a ball. This way you don't have to hold down
on any direction on your D-pad. While falling as a ball, you can enable
the spider ball to stop yourself before you fall to far and lose a hole in
The "Select Trick" works best on the original Game Boy model. On Game
Boy Pockets and Game Boy Colors, the "Select Trick" is much harder
