"Advent calendars are not just for Christmas anymore. What a great build up to my favorite holiday, Halloween! ♥♥♥ it!" -AudreyB
Open a different portal on the mysterious Caloween house every day throughout October-2011 to reveal the creature behind each portal. Find bugs, spiders, birds and maybe even a fun monster.
Oh, and if you want a scarier, night-time version of this app, look for Calloween™ (with two 'l's) which includes different and scarier inhabitants behind every portal.
