Llyfr rhyngweithiol sy’n cynnwys dwy stori ditectif o'r gyfres feithrin boblogaidd S4C, 'Llan-ar-goll-en'. Mae'r gyfres yn dilyn anturiaethau Prys ar Frys a'i bartner animeiddiedig, Ceri'r Ci-Dectif wrth iddyn nhw ddatrys dirgelion ym mhentref glan mor, Llan-ar-goll-en. Mae'r pentref ei hun wedi ei selio ar bentref enwog Portmeirion yng ngogledd Cymru.

An interactive storybook featuring two detective stories from S4C’s popular pre-school detective series, ‘Llan-ar-goll-en’. The series follows the detecting adventures of two super-sleuths, Prys ar Frys and his animated sidekick, Ceri’r Ci-dectif (Ceri the dog-tective) as they solve mysteries in their home village of Llan-ar-goll-en. The village itself is based on the famous Italiante village of Portmeirion, in North Wales.
