The Poké Radar is a tool used to find Pokémon that are hidden in the grass, but Cubone is not a Pokémon that is typically found hidden in the grass.
Here's why:
* Cubone is a common Pokémon that can be encountered in various areas, including routes and fields. You can find it by simply exploring the game world.
* Poké Radar is primarily used for finding rare Pokémon. While you can use it for some common Pokémon, it's more efficient for finding those that are harder to locate.
So, you can confidently catch Cubone without relying on the Poké Radar. Just explore the game world and keep an eye out for it!
