Since Pratt's new movie is all about dinosaurs, SA Wardega created some very convincing dinosaurs to scare him. The Polish pranksters set up multiple cameras, filming the
hallway that served as their setting.
Pratt can be seen approaching, and the fake dinosaurs lurked around the corner. Pratt, understandably, freaks out when he sees them,
exclaiming, "Oh s***! You motherf***ers … Oh great, you have cameras."
Pratt was very good-natured about the prank and was excited
to learn that these were the same people who created the scary "spider dog."
"You got me, man. That was good," Pratt told them. "You did a good job, you guys."
