I had Drago camping once, pity I didn't have space for him. Tia as well, same problem. I was really happy about getting Mint though, I still can't bring myself to let her go!
I had Bill camp twice in RainDrop, but since he was one of my original residents in Lancre, I didn't invite him to stay.
I had that little doll camping in my town the other day, but I have no room. I would love to have her in my town with Skye. It was just fun playing games with her.
Flora and Muffy are about the best I've gotten from the campsite -.- I have pretty terrible luck with it most of the time.
Stitches has shown up there before, but I don't really care for him and didn't know how popular he was at the time.
I got a new number one, today I found Ruby in my campsite!
I had a spare place in my town so I asked him to move in, I hope he moves in to a good spot to keep him a longer period of time.
