The Imaginary Corpse

Tippy the triceratops was once a little girl's imaginary friend, a dinosaur detective who could help her make sense of the world. But when her father died, Tippy fell into the Stillreal, the underbelly of the Imagination, where discarded ideas go when they're too Real to disappear. Now, he passes time doing detective work for other unwanted ideas - until Tippy runs into The Man in the Coat, a nightmare monster who can do the impossible: kill an idea permanently. Now Tippy must overcome his own trauma and solve the case, before there's nothing left but imaginary corpses.
