TJ's gran has hairy legs and arms. She also makes the best banana cake in the universe, as well as baked bananas, choc-coated bananas and Roast Lamb Surprise (which is mostly bananas) too. In fact, there is only one little problem about having a gorilla for a gran. And the little problem's name is Linda. What will cool clever Linda think when she finds out who tJ's gran really is? And what will she think of a pet who's a slimy Giant Skateboarding Slug called Egbert? Will she still want to perambulate with tJ? But then again, perhaps Mr Pifflewhiskers, their teacher, is not what he seems... When wombat poachers come to Gobbledygook - it's up to tJ and Gran, with help from Linda and Egbert - and a surprise discovery - to save the day.
