Nothing formal, its an open to the public sort of show and then they choose children in the middle of the show. They do some "Simon Says" type things, and I believe the pirates are watching which kids can listen well. Inevitably they select children older than toddlers, and probably have their own standards in their mind-- but nothing formal is posted, and all can watch and enjoy. At the very end, all children who want to are called up for the pledge and a little participation.
