first, you don't need to tag another ds to get avatar sectors. the game will randomly generate them over time in tag mode even when theres no one else around, just in case you weren't aware, but that can be time consuming... -_-
A faster way to get balloons to pop up in tag mode if you have a wii with internet connection you can open the nintendo channel and download any ds demo. once its transmitting, your ds will recieve the wireless signal and generate a random balloon on the screen pretty much instantly
(i've heard this works with other wireless signals such as other ds games in tag mode but this is the only method i've tried)
