How to Get Shiny Cascoon in HeartGold & SoulSilver
Cascoon bundles up in the National Park, but a shiny comes faster from Masuda breeding with a foreign parent. Compare Shiny Cascoon odds across every game
Shiny Cascoon Evolution
Multi-Path
HeartGold & SoulSilver Shiny Cascoon Calculator
2 MethodsThe best route is Masuda Method, about 1 in 1,639 on each try.
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.
How many you have done, or plan to do.
| Chance | Encounters | Time |
|---|---|---|
| 10%lucky few | 173-- | -- |
| 25%one in four | 472-- | -- |
| 50%coin flip | 1,136-- | -- |
| 90%very likely | 3,773-- | -- |
Time assumes -- at your pace and does not change your shiny odds.
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.
Want exact numbers for your session? Calculate your shiny odds in HeartGold & SoulSilver with Cascoon preloaded.
Cascoon Weakness
Cascoon is weak to Fire, Flying, and Rock. Cascoon's physical bulk (base 55 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 2x (Weak) | Fire, Flying, Rock |
| 0.5x (Resist) | Grass, Fighting, Ground |
- Fairy type does not exist — Dragon has fewer checks
- Physical / Special split now per-move (introduced Gen IV)

Cascoon Evolutions
From here, Cascoon's line branches into Silcoon and Cascoon. That's 2 possible evolutions, each with its own method. Defense has grown the most so far (+20), but there's still another 190 stats to gain in the final evolution. View every chain in the Evolution Chart.
How to Evolve
Breeding
Breed with Cascoon to get Wurmple eggs easily using 48 partners from the Bug egg group.

Moves List
