Pokémon Go celebrates the arrival of Pokémon Horizons: Season 2 with the debut of Tinkatink
The hammers you notice Pokémon holding serve a purpose beyond just looking cool. Tinkaton, in particular, uses them to fling rocks at Corviknight. Moreover, you can evolve your own Tinkaton by gathering candy throughout the week – approximately 125 Candy is required to reach its final form.
