Collection Strategy:

Since Fleas are spread across the entire map, it's recommended to collect them naturally as you explore each area rather than hunting specifically for them. This prevents backtracking and makes the quest feel less overwhelming.

Pro Tip: Mark areas you haven't fully explored yet, as many Fleas are in secret or hard-to-reach locations.
