Traveling Npc Idea's Needed

[Krynth]

Well first of all I want to know if this is a good idea or not having traveling Npcs sorta like Legend of Mana's traveling merchant bunny and FF9's moogle mail....

Carnival is something I'm going to do for sure but what about musicians and the other two?

That and what else is there that can be a traveling npc? Sorta out of ideas...

Musicians: Thinking of having 3 chipmunks (Probably change though) but they're going to be traveling to promote there lil band singing in there squeeky voices.....

Mail and Merchant: May just combine those with the chipmunks...(Merchant-they get stuff that they dont like so they trade you for nuts or something) (Mail: seeing how they are traveling they want fan-mail but cant always recieve it so you come in the picture and help)
