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 Thwackey is by evolving a Grookey.
