Frederico, The Mouse Violinist

Frederico is a tiny mouse with a big dream: he wants to become a violinist. Each day he watches as Stradivari makes his famous violins. Each night, he sneaks into the workshop to play. But the violins are too big! Then, unbeknown to Frederico, Stradivari sees him playing and begins carving a tiny device. Could it be a famous Strad especially for Frederico?
