Secret worlds
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 wall.
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 to perform.
