The Worm Pokemon. Found in Johto's National Park. Caterpie still hits Butterfree fast, but the competition for Bug-type team slots is fiercer in Gold & Silver.

Is Caterpie Good in Gold & Silver Playthrough?

Available in the National Park and on early routes. Butterfree comes quickly and provides the same MoveSleep Powder utility it always has. Less critical than in Yellow since Falkner's Flying gym isn't a matchup Butterfree wants.

Caterpie falls out of Headbutt trees around Azalea Town and Ilex Forest, and since one trunk can be struck over and over, camp a single rustling tree and keep hitting. Compare Shiny Caterpie odds across every game

2 Methods
Fastest Path

The best route is Breed w/ Shiny Parent, about 1 in 64 on each try.

Step 1 · Encounter Method2 in Gold & Silver

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

Breed w/ Shiny Parent: Eggs inherit stats from a shiny parent, so about 1 in 64 hatch shiny. A shiny Ditto helps every egg, and any other shiny parent (the red Gyarados works) helps only eggs of the opposite gender.

How many you have done, or plan to do.

ChanceEncountersTime

25%one in four19----

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
