"Where is Mr. Grill?" Jeb asked.
"He said to meet here."
"Maybe he forgot," Poppy said.
"I don't think so," Dipper said.
Everyone looked around.
But they didn't see the teacher.
"Hey!" Gasser said.
"What's this?"
Eddy saw a sheet of paper.
There was an oval on it.
"Hmm," Eddy said.
"It looks like a racetrack."
Poppy gasped.
"I bet Mr. Grill left it!" she said.
Everyone looked confused.
"Why did he leave it?" Zippy asked.
"So we can find him," Poppy said.
"I think it's a clue."
"Oh, fun!" Dipper said.
"Let's go to the racetrack!"
Everyone hurried to the racetrack.
Eddy saw a sign.
It said, "Race!"
