Trainers could find shiny Spheal in Pokemon GO as colder weather encroaches ahead of the game's Holiday season programming.
Niantic Labs' December Holiday season programming has officially gone live in Pokemon GO today, Dec. 22. From now until Dec. 31 at 10 p.m., local time, trainers will be able to encounter rare ice-types in the wild, from eggs, in raid battles, and more—alongside an exclusive research line. Spheal just so happens to be one of those Pokemon.
Shiny Spheal Pokemon GO
Unfortunately, Spheal has yet to have its shiny form implemented in Pokemon GO. It was originally added to the game along with the rest of the aquatic Hoenn residents with the 2017 Holiday programming on Dec. 21, 2017. It lacks both a shiny and Shadow form at the time of writing.
Spheal is part of a three-stage evolutionary tree made up entirely of ice and water-types. With the use of 25 candies, Spheal becomes Sealio. It can then be evolved further into Walrein with 100 candies. All three share the same light blue, white, and cream color palette.
When shiny, Spheal changes its blue coloring for a vibrant purple. Sealio and Walrein follow suit.
As mentioned before, Spheal hails from the Hoenn region as part of generation three. It has a PokeDex number of 363. According to its description, it finds rolling as a much faster form of locomotion than walking. When eating in a group, all group members clap their fins to show their enjoyment—"Because of this, their mealtimes are noisy."
Other Pokemon appearing more frequently, like Spheal, include Snover, Piplup, and the newest ice-type, Vanillite. Trainers can head to Niantic's Pokemon GO news blog for more information regarding the Holiday mechanics.
