Whistle of the Witch Varganax
From Jenny Everywhere Wiki
The Whistle of the Witch Varganax was an Artefact of Power which could be used to turn people into toads. It came into the possession of Sorceress Sally, one of the merchants at the Interdimensional Black Market, who kept it in a small silver chest under the counter of her stall. The Queen of the Black Market eventually gave it to the Wellsian Skollops ag-Warka (to give to Radluhac ag-Wampyr as an Allac-Ur present) in exchange for Skollops surrendering some information about the Clown Emperor.
