How to Get Cascoon in Emerald

Cascoon is the cocoon that leads to Dustox, uncommon at level 5 in the same woods as Silcoon. Catching it straight from the grass lets you pick the poison branch instead of leaving it to the Wurmple coin flip.

Where To Catch Cascoon in E

How to Get Shiny Cascoon in Emerald

Cascoon hides in the tall grass of Petalburg Woods as an uncommon encounter, so grind that patch, or evolve a shiny Wurmple from the same woods, for the full-odds shine. Compare Shiny Cascoon odds across every game

Shiny Odds

Both methods here share the same odds, about 1 in 8,192 on each try. Pick whichever fits how you play.

Step 1 · Encounter Method2 in Emerald

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

Breeding: Hatch eggs of this line; each egg rolls at the base shiny rate (no Masuda before Gen IV).

How many you have done, or plan to do.

ChanceEncountersTime
10%lucky few864----
25%one in four2,357----
50%coin flip5,678----
90%very likely18,862----
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.

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.
