Ghost-type fans, listen up: Pokémon GO is giving you exactly one day to hunt down one of the most adorable spooky Pokémon out there. The Phantump Catch Mastery event lands on Saturday, September 26, from 10:00 a.m. to 8:00 p.m. local time, and it's all about precision throwing and Shiny luck.

Phantump, the stump-headed Grass/Ghost-type, has long been a fan favorite thanks to its eerie-cute design. But its Shiny form—a pale, almost spectral version—is what's really driving trainers wild this weekend. During the event, your chances of encountering a Shiny Phantump will be significantly boosted through Field Research, free Timed Research, and paid Timed Research.

David Harbour's 'Violent Night' is dominating HBO Max charts, proving its staying power as the sequel approaches. Here's why this holiday action flick is a sleeper hit.

Throw Like You Mean It

The core mechanic here is simple: land Nice Throws or better, and you'll earn double XP and extra Candy for every successful catch. That means even if you're not snagging Phantump on every throw, you're still racking up rewards. Field Research tasks will focus on throwing accuracy, with encounters featuring Phantump, Cherubi, and Drifloon. Both Cherubi and Drifloon will also have increased Shiny rates and will appear more frequently in the wild, so keep your eyes peeled between PokéStop spins.

If you're serious about maximizing your chances, the free Timed Research track offers additional Phantump encounters plus XP, Stardust, and other goodies. For $1.99, you can grab a paid Timed Research ticket that adds even more encounters and rewards. And if you prefer to stock up, the Pokémon GO Web Store is offering a $1.99 ticket box that includes two Rare Candies.

Don't Wait—Timed Research Expires

Here's the catch: neither research track can be saved for later. All Timed Research tasks must be completed and rewards claimed by 8:00 p.m. local time on September 26. Once the clock strikes, Phantump Catch Mastery ends and the Harvest Festival begins. So if that pale little ghost has been missing from your Shiny collection, Saturday is your moment.

While you're planning your Pokémon GO session, don't forget there's plenty of other entertainment to keep you busy this weekend. If you need a break from throwing Poké Balls, check out Netflix's weekend movie picks or see what's new on Prime Video's binge guide. And for a nostalgic twist, M. Night Shyamalan's Signs is back on Peacock.

But let's be real—your priority on September 26 is Phantump. With boosted Shiny odds, double XP for accurate throws, and multiple research paths to extra encounters, this is a tightly packed 10-hour window. Set your alarms, charge your phone, and get ready to make every throw count.
