Pokemon Go's The Season of Heritage event features Incense Day with the Ice and Ground-type Pokemon, Swinub. Professor Willow has discovered some mysterious ruins with a mysterious door, hinting at an incredible power sealed within.

According to Blanche, this door's first mechanism requires Stardust to unlock, along with the local Ice and Ground-type Pokemon to help out. On Sunday, December 5, Swinub will be attracted to Incense from 11 AM to 5 PM local time. It'll have the exclusive move, Ancient Power, as well.

Some other Ground-types available include Onix, Cubone, Rhyhorn, Whooper, Phanpy, Barboach, and the rare Larvitar. These are available from 12 PM to 1 PM, 2 PM to 3 PM, and 4 PM to 5 PM. For Ice-types, players will have the chance to encounter Seel, Jynx, Snealsel, Snorunt, Snover, Vanillite, and the rare Galarian Darumaka. These Pokemon will also be attracted to Incense between the hours of 11 AM to 12 PM, 2 PM to 3 PM, and 3 PM to 4 PM local time.
