Izu-Mallow

Izu-Mallow is a canned cake brand, likely parodying the real-life equivalent, MALLOW (which often uses the handle izumallow for online purposes).

Its existence is evidenced by one of the possible messages that appear after doing /feed or /eat.

"You find a pack of Izu-Mallow in your backpack. You enjoy their marshmallow and biscuit flavor."
