Eddy, Jeb, and Gasser were playing.
"I love dirt," Jeb said.
"I love jumping!" Gasser said.
He drove fast toward a pile.
Gasser flew through the air.
Mr. Grill came outside.
"Good morning, students!" he said.
"Do we have safety class today?" Zippy asked.
"That's so boring."
"No," Mr. Grill said.
"We're doing something fun today."
"What is it?" Eddy asked.
"Tell us!" Poppy said.
Mr. Grill smiled.
"I'm not telling yet.
It's a mystery!"
"When will you tell us?" Jeb asked.
"This afternoon," Mr. Grill said.
"Meet me in the parking lot."
That afternoon the students met.
They parked in the parking lot.
"Um," Dipper said.
"Where is Mr. Grill?"
