someone new at our house

We have been privileged enough to have a real live superhero come live with us recently. He makes daily appearances, and while we are still working out the details of his superpowers, we are certain that: he wears a cape (sometimes goggles), he is really fast, he can jump off of tall buildings (furniture) (maybe flying?), he helps people (like setting the table at dinner), his super pose is somewhere between flexing and hands on hips, while he answers to "the Mighty Quinn" he is usually just called a "super here-you," and he sometimes comes with a half-pint sidekick.
