[Padfoot likes bunnies. Specifically, he likes chasing them, and one Sirius Black has gotten kind of bored of the strange Muggle devices and poking at various things like stoves. So he's turned to the obvious, when he gets bored. There's a fluffy black dog prancing about the hallway, chasing after the bunnies with happy barks whenever he catches sight of them.]
