After a long moment, Goose's head emerges from his bag, his beak bearing a plastic card which he presses to the scanner.
The bar on the scanner turns green and you hear an affirming beep and a loud click, indicating that the door is open. You close your eyes and breathe a sigh of relief.
When you open your eyes again, you see Goose's curved neck undulating as he struggles mightily to pull open the heavy door.
You: Oh, sorry. Goose, I've got it. Just let go of the handle.
*HONK*
You: Goose! Just let go of the handle! You weigh less than the door itself! It's a good thing you weren't trying to pull this job alone!
*Irritated HONK*
You: Look, I've got it open, okay? Remember the plan? The guards know that we're here! We have to hurry! Move!
Goose gives a muted honk as he crouches and waddles in behind you
You: Will you stop complaining for once and focus? We're going to have to get past at least one guard on the way up to the third floor.
As you make your way up the stairs, you hear muttering above you, the click of claws on tile, there's a security guard on alert up ahead!
The guard seems really distracted by its excitement about being a guard doge, but there's only one other way up to the third floor. You can either wait for the guard to pass, which will probably take too much time, have Goose distract the guard, or knock him out.
