The Boy Who Saved Worms

Worms happen to be nice creatures.
But some of them have, unfortunately, and often on rainy days, the habits of
crawling out in the middle of ways and streets.
That might end up very badly!
One of these days, Oscar is saving the life
of a Rainworm Princess.
Which takes himself, believe it or not,
straight down to The Under World.
Stunning adventures!
