Zippy spun his tires.
He spun them very fast.
Mud sprayed everywhere.
But Zippy didn't move.
Zippy sank deeper.
"Help!" he cried.
"I'll help you," said Mr. Grill.
The teacher pushed.
Zippy moved a little bit.
But then Mr. Grill sank too.
"Help!" he cried.
"Uh-oh!" said Dipper.
Poppy gulped.
Eddy looked at Jeb.
Jeb looked at Eddy.
"Let's clear that mud," said Eddy.
The two friends moved fast.
Shloomp! Jeb scooped the mud.
He put it in Eddy's dumper.
Soon everyone was free!
"Thank you," said Mr. Grill.
"You're welcome," said Eddy and Jeb.
Eddy zoomed along the path.
"I love driving off-road!"
Zippy groaned. "I don't!"
