If Camper Turtle is in the movie, the Trailer will introduce him like this in a dramatic voice:
IN A WORLD
*show planet*
WHERE TURTLES
*show some turtles*
GO CAMPING
*show turtle in tent*
ONLY ONE WILL BE BETTER THAN THE REST
* Show CAMPER TURTLE*
THIS WINTER
HARRISON FORD IS THE CAMPER TURTLE!!!! *Cue possible quote that will become famous when Harrison Ford says it (i.e. "Snakes. I hate Snakes. Why did it have to be snakes?" or "Great kid! Don't get cocky!")
