Mediocre conversion of the classic arcade Frogger for the Spectrum that takes place in prehistory, where a caveman must cross a 'motorway' full of prehistoric creatures, get in a ptedoractyl's lair (a maze also full of monsters), steal one of its eggs and get back home. There are six eggs, he must carry one egg at a time and a level is completed when all the eggs are stolen.
The poor graphics doesn't help this dull game much.
