How to Get Bonsly in Platinum

Bonsly is a rare Trophy Garden spawn that opens up only after the National Dex. The post-game gate plus a thin rate make this little rock tree one of the slower babies to find in the mansion grounds.

How to Get Shiny Bonsly in Platinum

3 Methods
Fastest Path

The best route is PokeRadar Chain at full boosts, about 1 in 200 on each try. Tune it below.

Step 1 · Encounter Method3 in Platinum

PokeRadar Chain: Chain shaking-grass patches without breaking the combo. The rate peaks at a chain of 40.

Masuda Method: Breed with a parent from a different-language game. Works on any breedable line.

Full Odds: Walk through grass, surf, or fish. Every encounter is its own independent shiny roll.

Step 2 · Boost Your Oddstap to add

ChanceEncountersTime

How is this calculated?

Every encounter has the same shiny chance, the Shiny Odds Per Try shown above. Each one is a separate roll that does not care how many you have already done, so the more you hunt, the higher your overall chance of at least one shiny. The formula below turns your odds and your number of tries into that combined chance.

chance after N tries = 1 − (1 − p)^N,  where  p = 1 / odds per try

Example at 1 in 8,192 (classic full odds): about 864 encounters for a 10 percent chance, 5,678 for 50 percent, and 18,862 for 90 percent.

The table above flips that around: it shows how many encounters it takes to reach a 10, 25, 50, and 90 percent chance at your current odds. Turning on boosts like the Shiny Charm, sandwiches, or chains improves your odds, so the encounter numbers drop.

These are estimates, not promises. Most games have no pity counter, meaning no guaranteed shiny no matter how many you hunt, so even Very Likely is not guaranteed: some hunters find one early, others go well past that point.

Where these shiny odds come from: Read our full methodology

Bonsly Weakness

Type-wise, Bonsly takes extra damage from Water, Grass, Fighting, Ground, and Steel. It resists 4 types, giving it decent defensive coverage. Bonsly's physical bulk (base 95 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
