So... I've just discovered streetpass items...

And I was wondering how do you obtain them. My son got his copy of the game, we streetpassed, and my mayor gave him an orange balloon. I've streetpassed with a few people and only one other mayor has given me a blue balloon. I've seen guides that lists streetpass items but how do you actually obtain them, and why do some mayors give them away and some don't?

I think it depends on how many times you streetpass someone. You get a different item after you've streetpassed the same person so many times I believe. Most of the time the first time you streetpass someone they won't give anything away but after you've done it a few times eventually they'll start holding things like balloons, pinwheels, or ice cream that they can give you.

It's based on how many times you StreetPass someone. Here's a guide from the ACWikia:

Balloon (2nd time)Balloon (3rd time)
Pinwheel (4th time)
Bunny Balloon (5th time)
Bubble Blower (6th time)
Heart Balloon (7th time)
Ice Cream (8th time)
Soft Serve Ice Cream (9th time)
Tweeter (10th time)

I haven't gotten a Streetpass Item yet. But a few days ago, I finally connected my 3DS XL to the Internet, and I got the current Nintendo DLC the Aries Rocking Chair, my first Spotpass item.

Adding on to this: If you StreetPass with a specific person again after the tenth time, you'll get a random item (balloon, pinwheel, etc.).

You can order balloons from streetpass houses, if they have them in their house, of course.

I streetpass with my daughter all the time, so I have gotten quite a few of the items, but not all of them yet.
