The dragon and Shamus
In this chapter
With Grand Dizzy's egg, into the dragon's den for the shamrock; the minecart to the grasslands; the shamrock for Shamus, and the match behind him.
Back into the mines by the funnel, down the lifts to the deepest tunnels, and up the east lift to the plunger room. Through the blasted wall, the chamber beyond leads straight up into the dragon's den.
A dragon doesn't burn someone carrying an egg. With Grand Dizzy's golden egg in hand, walk right to the back of the den and take the solid gold Irish shamrock (The dragon's den). Once Dizzy has gone that deep the dragon is awake for good, and from then on it fires because he holds an egg: drop the egg there and leave the den's second egg alone.
Back out through the chamber, the lifts and the railway level to the minecart; this time steer for the branch that ends on the grasslands, east of the pond (The minecart).
On the high path, drop the shamrock in front of Shamus: he catches it and lets Dizzy by (The little fellow on the high path). Behind him lies the dry match.
