can you only find a halo rappy online and is it only on halloween or the whole month? :S
Look man, wait patiently, don't double post (one minute from each other! :O) asking if anyone's here! Don't expect an answer right away.
As for your question, by my understanding the rappies come out for a week.
Last year they were out longer than a week (a month I think..). Halo rappys appear only online like I stated in another thread.
