The Dirt Pile

" Gasser is a monster truck, " Dipper said. " But he's really nice. "

" I'm Carlin, " said an old van. " What do monster trucks do?"

" I drive on dirt, " Gasser said. " I also jump over stuff. "

" That sounds fun, " Carlin said. " It sure does! " Grandma said.

" Ha-ha, Grandma, " Dipper said. " You don't jump over stuff. "

" Come on, " Carlin said. " We'll show you kids around. "
