This is Marvin the (mini) hedgehog. Marvin is a quiet guy, and his greatest love in life are books.
Of course, such a little guy often has trouble opening the huge, heavy books we have around the place, so he's content to just sit on the bookshelf and peer over your shoulder to read.
He's often seen carrying around his own little book with him, bookmark and all...because honestly, what's a hedgehog gotta do to keep himself entertained? Otherwise, he's seen reading with his mommy hedgehog, or just daydreaming on plants...
Just make sure never to call him small when he's around...he IS, after all, at least as big as a lego brick, which is a whopping 5 cm long!
