Cupid Arrow
Cupid Arrows were the otherwise-harmless arrows used by the members of the Crew of the Copper-Colored Cupids to “romanticise” their targets using a magical “Love Potion” that filled them with a sense of universal platonic love. (PROSE: The Green Gorillas, The Winter Quests)
By 1994, the Crew kept a supply of Arrows in their “emergency supply warehouse” on the Prime Earth, with a number being stolen by the Mob of the Maroon Magpie until the Cupids, in defeat, abandoned the emergency supply warehouse and moved its contents to another location unknown to the Magpies.

When Larrikin-1029 tried to romanticise Madame Tarsa during the Cupids' first direct encounter with her, she plucked the Arrow out of the air and analysed it, allowing her to begin developing an ersatz Love Potion. However, Larrikin, Pessimist-242 and Pessimist's Fog Ship subsequently destroyed her research before she could complete her first batch. (PROSE: The Toymaker's Labyrinth)
