Shiny Hippopotas Pokémon GO: How to Catch

Pokémon GO celebrates the Sinnoh Region, the fourth region Nintendo introduced to the Pokémon universe, with a special in-game event Friday. The event began at 8 a.m. local time and is scheduled to continue through the weekend, ending Monday at 10 p.m. local time.

Throughout that period, all 7 kilometer eggs will hatch Pokémon from the Sinnoh region. There are 14 Pokémon in the pool, including Hippopotas. The odds of hatching a Shiny Hippopotas from those eggs are not currently known. For reference, encountering a Shiny Pokémon in the wild happens approximately one in 450 times.

Players can collect eggs from Pokéstops. Those searching for a Shiny Hippopotas will want to grab and hatch as many eggs as possible in their pursuit.
