Greenie goes for a walk and climbs over a big mountain, crawling through a dark spooky tunnel underneath. In the tunnel, Greenie sees two fierce yellow eyes but turns back, hoping the monster is friendly. After struggling for weeks, Greenie reaches the top of the mountain but heavy clouds obscure his vision. Slipping on a loose rock, Greenie falls 3000 meters into the sea. Spotting a treasure chest and shark, Greenie swims to shore for safety.
