Aunty Em's Gnome Emporium

Aunty Em's Gnome Emporium is a garden statuary shop outside New York City, off the main highway. It at first appears to be run by a kindly middle eastern woman who offers to feed Percy, Annabeth and Grover for free. However, it soon becomes clear (at least to Annabeth) that something is amiss and Aunty Em turns out to be none other than Medusa.

Grover even recognizes his Uncle Ferdinand among the statues.
