Sinnoh Celebration- Riolu and Hippopotas Shiny Rates

Greetings, travelers! The month of February is bringing a flurry of events to Pokémon GO. This week, we have yet another reason to celebrate! From February 7 to February 10, Pokémon from the Sinnoh region are being highlighted in the wild, raids, Field Research, and Eggs. Travelers are treated to two new shiny species during this event: Riolu and Hippopotas! As always, our enthusiastic Silph Road Researchers have hit the ground running to bring you the shiny rates of these two Pokémon. Let’s see what they have found so far!

The Sinnoh Celebration is coming to a close around the world. So far, researchers have uncovered a total of 3,756 Hippopotas from all encounter methods (with wild encounters being the vast majority) with 9 shiny Hippopotas. These data give a 99% confidence interval around the shiny rate of 1 in 200 to 1 in 1200, giving no evidence that the shiny rate for Hippopotas is boosted.

Researchers also tried their luck at tracking Riolu, and hatched 166 total Riolu, with 3 being shiny. These data are not sufficient to make strong conclusions about the shiny rate for Riolu. The 99% confidence interval for the shiny rate stretches from 1 in 20 to 1 in 485. As always, we will keep you updated if anything changes. Until then, stay safe on the Road, travelers!
