I lost my cycling cartridge... again. A big house can be a pain sometimes... Any prominent places I should look? I looked in my room ALL over, so it wouldn't be in there, I checked in both couches, the TV cabinet, and two tables where I usually put it when I play.
Have you had a look inside the baby cage? Have you tried under the meat discombobulation unit? How about the holographic mammary device? Checked behind the inverted hydrophobia containment silo?
Sorry if I'm not much help, but I can't be much more specific since I don't know what your bloody house looks like.
