The Dragon Coaster
The dragon is keeping watch over his
treasure and you will see him as you go
around on the dragon ride.
He is operated by three
different motors that
assist him to move
forwards and
backwards, move his neck
left and right and move his
head left and right. He
moves when a signal is
received by sensors telling
him that a train is arriving.
Study the Dragon as you go past and think of what set of instructions he might
be following.
