Luckily, Mushu's managed to escape from Cross's place fairly unscathed. He's a little bit alarmed now -- who knows what other kinds of scary people m might be around?? -- but he's alive and that's what's important.
Maybe if he tries a second floor, he'll have better luck? And look, there's one right there. Over a lawn, up a tree, and over the windowsill, and Mushu finds himself inside! Victory!
....But not quite, because in his relief over getting in, he accidentally bumps into a pen holder and knocks it off the desk.
