Scooby and Shaggy stay completely still. The cart teeters on the edge of the mine shaft.
“Ahh, ahh!” Scooby gasps as dust tickles his nose.
“No, Scoob, nooooo!” Shaggy yells.
ACHOO!! Scooby lets out a monstrous sneeze. The cart plunges over the cliff!
Shaggy and Scooby fall. And fall. Until they splash into an underground river. The current is gentle, but then they hear the roaring sound of rapids.
“Ruh-roh,” Scooby whimpers.
The pals almost fall out of the cart as it bounces over the rocks, but there is more danger ahead of them.
“Zoinks! A whirlpool!” Shaggy cries.
