Red - Increases Neopoints earned when playing games. Blue - Lowers Shop Prices. Green - Increases Random Events. Yellow - No idea. Hmm, I think this promotion is pretty popular cause TNT just release another promotion for Lutari island in Taiwan.
I hope not many, myabe next time they'll think twice before they dedicate something outside of neopets
+rep you gave answer to my question, if you could find out what the yellow beads are for, you are the bomb :roll:
Are you asking about the promotion or the beads? There's a rumour that the yellow one increases the chance of getting good items from dalies but it isn't confirmed. EDIT: thanks for the +rep
