Through the Loupadapper Marshes — Paul Cook

Book 2 of 'Wappy Ding-Do Trilogy' charts the encounter by the entity with the loupadapper and the hybrid species that spawns from a chance alteration in their DNA sequence. This short story is suitable for readers aged eleven years and older. The book is written by British author Paul Cook who is also the author of the 'Pete the Bee' stories.
The wappy ding-do kind of was but, well, sort of wasn't either. Perhaps something more than a soul of mere essence, but somewhat less than a corporeal presence. The wappy ding-do was, in fact, a globule of glandular lesions and fibroid connectors, invisible to the human eye but nevertheless tangible in a unique spectral, fluid-like, temporal universe.
