Last week, the Winx returned (with the Specialists) to Paradise Bay, where Brandon picked some flowers for Stella, and apparently the denizens of the Leaf Miniworld weren't too happy about that...
Zap2It summary:
After Chloe explains what has kept Paradise Bay alive, the Winx realize that they must grow new gems of light.
Well this created a new concept of interlinked mini worlds even if you cannot directly travel between the two. Sadly not explored further
Well what a way to travel and this was supposed to be a serious mission. It does feel like it loses its momentum when the Winx are having fun and then promptly switched back to serious again.
