Flexible Survival

I have been to new ewe and have tried hunting underneath the mall for littlelostlamb as the wiki said to do but was told that "You don't think what you're looking for can be found here...". I also tried hunting "mary", "little lost lamb", "lamb", "maryyene", and "lost lamb" as well as just going down alot but I haven't found Mary. What am I doing wrong?

Did you encounter the New Ewe Store event twice? You need to have found Mary in outside exploration before you can find her in the sewer.
