That scary moment when an AI velociraptor learns to open doors

Plastic Dinosaur's normal living space is a big warehouse with a lot of interesting features for it to clamber over and peer behind. But it's noticed that the bipeds he shares the space with come and go through parts of the barriers that contain him. He's noticed that they can swing part of the barrier open, pass through the opening and then the barrier closes behind them. He's seen space behind the barriers that he hasn't explored. Plastic Dinosaur wanders over to the door, peering at things as he goes to see if anything more interesting shows up.
