This was one of the random-est episodes of Winx I've ever watched.
And their science facts were off. Bananas can't reproduce naturally because us humans have artificially selected them to have tiny seeds that are sterile. By bringing back a prehistoric banana you're going to bring back bananas with big seeds that modern day lemurs probably can't chew on or digest. Anyways, back to winx, bio is still on the brain from the exam...
I didn't hate it, but I didn't love it.
Stella is forever being picked on in this season though; she's always the unfortunate one.
