Pokémon Go has been a flub in terms of recent updates. Both the Valentine’s Day and World Water Day updates disappointed players, which is why the game’s parent company, Niantic needs to come out with a new one, which generates players’ interest in the game again.

The company is expected to announce an Easter event before Sunday. Niantic could possibly hold an egg-themed event, which could bring changes to how the Lucky Eggs work — they would last twice the time they normally do.

Gamerant reported last Friday that players would be likely to discover more eggs at Pokéstops. These eggs might have the look of traditional Easter eggs, basically giving players Pokémon trails the feel of an Easter egg hunt. Hatching time for eggs could also be reduced, so players might be able to get their hands on more Baby Pokémon.  Increased numbers Pokémon that feature eggs including Blissey, Chansey, Togepi and Exeggcute, might be available in the wild. Furthermore, Niantic might also be reducing the price of Pokémon Go Lucky Eggs.

Just like previous events, Niantic could offer double XP and more candy. The company might also come out with five new Legendary Pokémon — Articuno, Zapdos, Moltres, Mew and Mewtwo, according to Birmingham Mail.

Another possibility is that Niantic might come out with Shiny Pokémon — Shiny Magikarp and Shiny Gyarados have already become a part of the game following the World Water Day event. This would mean that more water-type Pokémon could spawn globally, in all biomes Slashgear reported on March 30, citing anonymous sources.

In terms of spawning, the rate of spawning could be increased for rare Pokémon, new Pokémon and shiny versions of existing Pokémon might also spawn. According to Express U.K., dataminers have discovered new redeemable codes for items such as Avatar accessories, Candy, Stardust and Pokémon, which could be made available during the event.

While Niantic hasn’t put any information regarding the event, it did tease a co-op gameplay feature in a recent announcement.
