When Porridge was a small kitten he toppled into a tin of tartan paint -- which is easy to do and not so easy to say.
Now he lives by Loch Loch with the quirky McFun family: Gadget Grandad, Groovy Gran, Dino Dad, Mini Mum and the twins, Roaring Ross and Invisible Isla.
Everyone has a super secret-- or two-- and Porridge is always there to lend a helping paw when things go awry.
If there's a fishy biscuit in it for him...And things do often go awry in the McFun family.
It's a good job Porridge has nine lives!
Porridge the Tartan Cat (it's a long story involving a tin of tartan paint!) has discovered Gadget Grandad is not your average snoringly boring grandad after all!
He's a super-duper secret spy -- and he needs help from Porridge (the cat, not the gloopy breakfast) and the twins Isla and Ross to defeat his arch enemy Fergus McFungus.
McFungus has stolen the super secret recipe for disaster.
Can Porridge and the twins help?
