You finally made it past the Elite Four. You’ve crossed the border back into Kanto, ready to reclaim your nostalgia, only to realize the original Fuchsia City Safari Zone is a total bust. It’s a zoo now. Warden Slowpoke has moved on. But then you find it—the Pokemon Heart Gold Safari Zone tucked away in the Johto wilderness, west of Cianwood City.
It's a headache.
Most people remember the Safari Zone as a simple walk in the grass where you throw mud or bait. In Heart Gold and Soul Silver, Game Freak decided to turn it into a bizarre, time-gated customization simulator. It is easily the most complex mechanic in the generation four remakes. If you’re looking for a Riolu or a Gible, you aren't just looking for a patch of grass. You’re looking for a specific arrangement of "blocks" that might take over two months of real-world time to actually function.
The Customization Trap
Baoba, the guy who runs the place, is ambitious. He lets you move entire biomes around like some sort of ecological god. Want a desert next to a forest? Done. Want a marshland next to a mountain? Sure.
But here is the kicker: the game doesn't really explain the math behind the "Object Arrangement" system. You get six areas at a time out of a possible twelve. Each area can hold 30 decorations, or blocks. These blocks—like small rocks, trees, or fountains—are the keys to unlocking the rare stuff.
Basically, every Pokemon has a point requirement.
If you want a Larvitar in the Mountain area, you need 5 Peak points. A small rock gives you 1 point. Simple, right? Put five rocks down, and the Larvitar shows up. It gets weird when you start hunting things like Bagon. For a Bagon, you need 9 Peak points and 19 Forest points in the Peak area. But you can't just slap those down and expect a dragon to appear.
The Infamous Time Gate
This is where the Pokemon Heart Gold Safari Zone loses most players. There is a hidden "area level" mechanic. Every area stays at level 1 for the first ten days you have it active. After 10 days, the value of certain blocks doubles. After 30 days, they might triple. By day 120, a single block might be worth four times its original value.

Why does this matter? Because some Pokemon require a point total that is literally impossible to reach with only 30 block slots unless you wait for the time multiplier to kick in.
Take Gible. To get a Gible in the Waygate area, you need 28 Rock points and 35 Forest points. If you try to do this on day one, you’ll run out of space to put blocks before you ever hit the requirement. You are forced to wait. You have to leave that specific area in your active rotation for 100 days before the blocks "mature" enough to summon the Gible.
It’s brutal. It’s a test of patience that most modern games would just let you bypass with a microtransaction. Back in 2010, you just had to stare at your DS calendar and sigh.
Does the DS Clock Trick Work?
Kinda. But it's risky.
If you change the date on your Nintendo DS system, the game often detects the tamper. The Safari Zone clock is tied to the transition of midnight. If you jump the clock to 23:59 and let it roll over, you can sometimes trick it, but Heart Gold is smarter than the older GBA games. If you mess it up, you might actually freeze your daily events, meaning you're stuck waiting even longer for Baoba to call you with new challenges.
Most experts, including the folks over at Serebii who spent years deconstructing the RAM values for these games, suggest just doing it the "honest" way. Put your blocks down, save the game, and go play something else for a month.
The Two Tests of Baoba
Before you can even touch the blocks, you have to pass two tests. Baoba is picky. First, he wants you to catch a Geodude in the Peak area. That’s the easy part. It’s a rite of passage.

The second test is the real hurdle: catching a Sandshrew in the Desert area.
This sounds easy, but it’s the game’s way of introducing the Area Creator. You have to physically go into the computer, swap the current terrain for a Desert, and then go hunting. Once you finish these, Baoba eventually calls you—it takes about three hours of in-game time—to tell you that you can finally start placing objects.
Hidden Mechanics Nobody Mentions
People often forget that the "bait" and "mud" system is actually a math equation.
- Bait: Makes the Pokemon less likely to flee but harder to catch.
- Mud: Makes the Pokemon easier to catch but much more likely to flee.
In the Pokemon Heart Gold Safari Zone, the catch rates are notoriously low for the rare spawns. If you're hunting a Metang, its base catch rate is already bottom-tier. Throwing mud feels like a gamble because that Metang will likely bolt the second the ball breaks.
Honestly? Most of the time, the best strategy is to just throw a Safari Ball. Every turn you spend throwing bait is a turn the RNG can decide to end the encounter. It’s a "press your luck" mechanic where the house almost always wins.
The 12 Areas You Need to Know
You can’t have all the biomes out at once. You have to pick six. If you swap an area out, it retains its "level" (the time-gate progress), but it stops gaining days.
- Plains: Good for Shinx and Lotad.
- Meadow: Where you'll find Riolu (after a massive 70-day wait and 42 Peak/Object points).
- Savannah: The place for Luxray and Torkoal.
- Peak: Essential for Magmar and Bronzor.
- Mountain: Home to Larvitar and Lickitung.
- Desert: Where Trapinch and Cacnea hide.
- Wasteland: High-level stuff like Skorupi.
- Wetland: Sliggoo precursors and Quagsire.
- Swamp: For the rare Carnivine.
- Marshland: Croagunk is the big prize here.
- Forest: Look here for Beldum and Misdreavus.
- Moor: A mix of water and land types.
The Riolu Grind
The most searched-for Pokemon in this entire zone is Riolu. Everyone wants the blue dog. But getting Riolu is a nightmare.

You need the Meadow area. You need 42 Peak points. Since you only have 30 slots, you cannot get 42 points using basic 1-point rocks. You have to wait for the 70-day multiplier to turn your rocks into 2-point or 3-point powerhouses.
This means if you bought the game today, you wouldn't be able to catch a "natural" Riolu in the Safari Zone until well after you've finished the Kanto gym leaders. It’s a post-game commitment, not a casual catch.
Why Bother?
With the modern "National Dex" being a thing of the past in newer games, why do people still obsess over the Pokemon Heart Gold Safari Zone?
It's the Safari Ball.
In the competitive Pokemon scene and the "Ariball" collecting community, having a Pokemon in a green-and-white Safari Ball is a status symbol. Since you can't buy Safari Balls in any other game, the only way to get a "legit" Safari Ball Garchomp or Lucario is to catch the base forms right here in Johto and transfer them forward through the Poke Transporter and Pokemon Bank.
It’s about the flex.
Actionable Strategy for Your Next Run
If you’re booting up Heart Gold or Soul Silver right now, don't wait for the post-game to start the Safari Zone clock.
- Rush to Cianwood: As soon as you have Surf, get to the Safari Zone.
- Complete the Tests Immediately: Don't let Baoba's requests sit in your quest log. Get the Geodude, get the Sandshrew.
- Set Your Biomes Early: Decide which rares you want (Gible, Riolu, Beldum) and place those areas in your active six.
- Place "Dummy" Blocks: Even if you don't have the right blocks yet, filling the slots helps you track what you need.
- The Midnight Roll: If you do decide to skip time, always set the clock to 23:58, enter the game, wait for the clock to hit 00:00 in-game, save, and repeat.
The Pokemon Heart Gold Safari Zone isn't a place for the impatient. It's a slow-burn strategy game hidden inside an RPG. Understanding that the blocks aren't just decorations, but literal mathematical triggers, changes the whole experience. Stop treating it like a park and start treating it like a puzzle.
Check your area levels by talking to Baoba regularly. He won't give you a spreadsheet, but he’ll hint at how much the "popularity" of the zones has grown. That’s your cue that the multipliers are working. Once those 100 days pass, the rarest Pokemon in the game are finally yours for the taking.
