Yes, you can catch the shiny version of Pumpkaboo in Pokemon GO, but it is very rare.
Whenever you encounter a Pumpkaboo in Pokemon GO, there is a very low chance that it will be shiny. This is the case no matter how you encounter it.
If you are searching for a shiny Pumpkaboo in Pokemon GO, there’s no better time to catch one than during the October 17 Pokemon GO Spotlight Hour. This is because Pumpkaboo will be spawning much more frequently during this event!
Pumpkaboo Shiny Odds
The odds of any Pumpkaboo you encounter in Pokemon GO being shiny are 0.2%, or 1 in 500.
This means that, on average, you’ll need to find 500 Pumpkaboo before you find the ultra-rare shiny version.
Unfortunately, there is no way of boosting shiny odds for any Pokemon in Pokemon GO. This includes Pumpkaboo.
What Color is Shiny Pumpkaboo?
The shiny version of Pumpkaboo has a purple body with green circles on it and a black head.
This makes it appear very different to the standard version of Pumpkaboo, which is orange and brown.
