She was holding a sea creature known as a Southern California Solitary Anemone. The Solitary Anemone has a body that is shaped like a big can or cylinder that can be as much as a foot tall and ten inches across. Seeing Stacks holding this thing was odd since most Anemone, the Solitary Anemone included, have a ring of stinging tentacles which surrounds its mouth. These tentacles contain a toxin which can paralyze and have been known to even cause death.
