Shim-bay crispa was a sweet treat, a dessert. The criminal called the Tombat orchestrated a scheme during a feast held for esteemed attendees of a major performance of The Kallea Cycle on Brentaal IV, in which quella stones were incorporated into the baking of the crispa. A number of those present, among them Zanza Gata, the Imperial Office of Criminal Investigations operative heading up the inquiry into the Tombat, suffered injuries to their mouths from biting down on the dessert.
