You would be in a shipping container. You're a large male Spinosaurus, and apparently, you've been captured to mate with a female inside of some theme park. When you get there, the truck is backed up into a large gate, and the container you're in gets opened. You step out of the to see a large habitat. There's a water fall and a crane that lowers food. After a few minutes,you see the female, Spinni. She sees you and starts getting excited.

Spinni: "Oh my god! You're here after so long!"
