How long does it take for berries to grow once you've planted them?

1. Look at the Berry Status screen, which may or may not clairify the time required before it is ripe enough to pick. Just look in the Berries part of your Pack, select a Berry, and select "Check Tag". But if they have stopped growing all of the sudden, this may be a case when you need to get a Berry Update at GameStop or EB's, which is what I did. You'll get hooked up to the sample GameCube they have there and spend a minute sending info. Have an extra space in your party, cause your gonna get a shiny Zigzagoon with a Leichi Berry.

2. Go to every object in the room and press A from every direction, including the windows, plants, and doors. I mean EVERYTHING in the room, even the carpet if there is one.

1. They differ...some take about one day while others grow in 12 hours...

2.Check every item in the house and also try hard to see spots from where you walk in (try the windows or the dressers).

Well first off, how did you get thirty Masterballs. Second, if you did throw a masterball, you would have caught it no problem. Third of all, just because it has low health, doesn't mean you catch it. Try putting it to sleep or use timerballs.

Different berries take different amounts of time to gorw, but they grow faster if you water them with the Wailmer Pail.

As for the Trick House, there is actually a sparkle there but you just have to look harder. I had trouble with that too.

Just look around and you'll find him. 6 of the places he hides are:
under a cushion
in both plants
behind both windows
in a cabinet
If I remember the others I'll tell you.
