Studying in the Castle

I'm studying for some chemistry and music theory exams I have tomorrow. Sir Velcro is helping me out, and Princess Bubbles is over in her tank scurrying around with a new cardboard box. Princess Stella is sulking because I accidentally closed a door on her. Not sure where she ended up. She'll be back. Velcro is getting mad that I'm not petting him with both hands. Got to go appease him!
