Mine associate with "good and bad" pirates because they love Jake and the Neverland pirates at the moment. I think that is enough now that they know there are good ones and bad ones and that at some stage we would go into more detail about it but for now if they want to pretend to be Izzy and Jake being pirates and helping others then Im ok with that - having said that, they haven't yet pretended to be Hook doing naughty stuff!
