Sure! In 1-P Befriending, you can meet, greet and be best friends forever with anyone ranging from King Altador to Hubrid Nox. Why, even Balthazar is a potential friend in the Befriending Dome! As long as you're not a faerie, of course. *sigh*
In 2-P Befriending, you can meet other Neopets users and make friends with them. Eventually, we will be expanding this feature to allow you to host Parties for all your friends. You will be able to send mass invitations by Friend type, hosting a party for Best Friends only, for example.
