Pokémon Go Sizable Surprises event guide: All bonuses, boosted encounters, and raids

The first big Pokémon Go event for April is here, and it’s a doozy with multiple new Shiny Pokémon appearances and other surprises. There might be a lack of Research options this time around, but the Sizable Surprises event does offer other bonuses and content to make up for it.

Set to run from April 4 at 10am local time to April 9 at 8pm local time, the Sizable Surprises event kicks off the Pokémon Go April event schedule—but continues an unfortunate 2024 trend regarding wild Pokémon spawns. During this event, you are more likely to encounter Shiny Wailmer and Pokémon sized XXS or XXL, along with Shiny Pokémon making their debut. And that is only the start of what this Pokémon Go event has to offer. 

Pokémon Go Sizable Surprises: Full event content guide

As the Sizable Surprises name suggests, the main gimmick for this event is seeing Pokémon known for being big or small more frequently. This includes Pokémon like Wailmer, which is a main focus of the event—since it will have boosted Shiny odds if you encounter one in the wild. 

During this event, you will also have a chance to encounter Shiny Wimpod, Shiny Celesteela, and Shiny Kartana for the first time. Unfortunately, Celesteela and Kartana are still exclusive to five-star raids in the Southern and Northern Hemisphere respectively, limiting their availability for the time being.

With content like that up for grabs, here is a full overview of every Pokémon appearing, raid happening, and event bonus available during the Sizable Surprises event.
