When Victor walks up to the box what he notices are the holes cut into the top. He isn't sure what to make of that until he takes off the lid and hears a very familiar bark before Makkachin pokes her head out over the edge of the box and licks him on the face.

She ends up tearing the box by leaning too heavily on the edge and then falls over on top of him, knocking him down.

At first, he's too stunned to realize what is fully happening, but then she's there and just begging to be pet and loved.

"Makkachin?" he asks, and then he laughs, and pets her carefully on the head. He doesn't seem to mind that he's sitting on the floor now with her on top of him. All that matters is that she's here.
