How to Get Gloom in Ruby & Sapphire

Gloom is the rarer wild follow-up to Oddish, with 12 encounters across three areas including the Safari Zone. It mostly shows up as a rare catch in the high 20s, so it takes patience.

3 locations to catch Gloom

Encountered via tall grass encounters

Badge 6

Where To Catch Gloom in RS

Oddish gets you Gloom sooner: catch it (before Badge 3) and evolve it at Lv 21. Wild Gloom first appears at Safari Zone (after Badge 6).

Want the exact numbers? Work out your catch odds in Ruby & Sapphire for Gloom.

How to Get Shiny Gloom in Ruby & Sapphire

Gloom appears rarely in the grass of Route 121, Route 123, and the Safari Zone, so keep cycling encounters until a shiny shows. Compare Shiny Gloom 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 Ruby & Sapphire

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.

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.

Where these shiny odds come from: Read our full methodology

Pokedex Entry

GLOOM releases a foul fragrance from the pistil of its flower. When faced with danger, the stench worsens. If this POKéMON is feeling calm and secure, it does not release its usual stinky aroma.

From its mouth GLOOM drips honey that smells absolutely horrible. Apparently, it loves the horrid stench. It sniffs the noxious fumes and then drools even more of its honey.

Gloom Ruby & Sapphire Guide

  • How do I catch Gloom in the Ruby & Sapphire Safari Zone?

    See the Locations section above for where to find Gloom in Ruby & Sapphire.

    Safari rules: You can only use Safari Balls. No battling. Two tactical items shift the catch/flee trade-off:

    • Throw bait to keep Gloom from fleeing (flee rate cut to 1/4) but it becomes harder to catch (catch factor halved).
    • Throw a rock to make Gloom easier to catch (catch factor doubled) but it flees twice as often.
    • Each effect lasts 2-6 random turns; throwing one cancels the other.

Game Availability

Present since Red & Blue, Gloom appears in 20 games spanning 9 generations. Gen 1 originals like Gloom have the longest track record of availability in the series.
