Gimmighouls manifest in two distinct forms: the Roaming Form, resembling bugs with coins on their backs, and the Chest Form, hidden in ruins and towers. Capturing Gimmighouls is exclusive to the Chest Form.

The Roaming Form, though elusive, can't be caught. You may encounter them around ruins, Pokémon Centers, bridges, and signs. Recognizing them is easy, as they emit a distinct growling stomach-like cry. Interacting with a Roaming Form gimmighoul evolution yields a collection of one to 200 Gimmighoul Coins, as per Serebii.net. These creatures tend to reappear, so revisiting spots where you've spotted them can be rewarding.

Conversely, Chest Form Gimmighouls offer more coins, ranging from 30 to an auspicious 777, but they have specific spawning locations and are active throughout the day. To acquire their coins, you must either defeat or capture them in battle.

Our strategy for coin accumulation involves actively seeking Chest Form Gimmighouls while revisiting ruins, marked on the map, to interact with any Roaming Form Gimmighouls.

For determined hunters of Chest Form Gimmighouls, Serebii.net offers a map with their exact locations.
