It's in the book, A Touch of Fever. After it was collected, Artie wanted to "try it down in the main collection first" because of how expensive Dark Vault storage was (really, budget issues were only ever mentioned in the book) and if it acted up (which it did when Claudia got a hold of it), it was moved to the Dark Vault.
