I ended up trading her away and kinda regretted it after a bit. I thought she was a fun if slightly disgusting looking pet.
I would look now and again to see where she was and who she was owned by. Last time I saw Lurgy (I took a lengthy mara-break) she was a candy Raulf.
Today I thought I'd look again "This pet does not exist" Wait...What?
I went to create a pet and surely enough Lurgy was available. I snapped the word up, turned him into a slime xoi and shortly after I was lucky enough to be able to purchase an enchanted gobble plushie (huge thanks to the seller <3 )
I then re-costumed slime and voila.. The drippy, cold filled Lurgy is back on my profile to sniffle another day!
