Sebastian Snail on the Treasure Trail

A bored Sebastian Snail decides to sort through all the stuff in the attic of his stately home, Pail Manor.
As he sorts through things long forgotten, he finds an old map which, to Sebastian's eyes, looks like a treasure map.
Along with his friend, Caruthers Caterpillar, he hatches a plan to find the family treasure, but without interference from his snooty butler, Snodgrass Hopper.
And so, secretly, they set out with the map, with no idea of what lies ahead of them!
