Rillaboom is the Grass-type starter of Galar, the 8th Region in the franchise. Though, that region is not available to explore in PRO. It evolves from Thwackey as early as level 35 and is the final evolution of Grookey.

Obtainability

Spawn Information Temporarily Unavailable

Since 17 July 2026, the public Spawn Dump Page has been temporarily disabled and will remain unavailable for an indefinite period.

Because the Pokémon Revolution Online Wiki relied on this data source, it is currently unable to display spawn locations.

For the time being, please rely on the in-game spawn information instead. Spawn information will return once a public data source becomes available again.

The primary way of obtaining a Rillaboom is by evolving a Grookey.
