Beads are the primary currency in Yoshi's Woolly World. You'll find them scattered throughout every level, often in large quantities. They are essential for purchasing Power Badges before starting a level. Here's what you need to know about beads:

- Collecting: Simply touch beads to collect them. They often appear after defeating enemies, hitting clouds, or in bonus rooms.
- Spending: Before entering any level from the world map, you'll have the option to visit the 'Badge Shop'. Here, you can spend your collected beads on Power Badges.
- Farming: If you're low on beads, revisit earlier levels, especially those with many enemies or bonus rooms, to quickly stock up. The 'Magnetize Beads' Power Badge can significantly increase your bead collection rate.
While not a collectible for 100% completion in the same way as Wonder Wools or Smiley Flowers, beads are vital for making your journey easier by allowing you to purchase helpful Power Badges. Don't underestimate their value!
