The Classical Composers Musical Caterpillar Trumpet introduces little ones to three favorite brass instruments. By pushing one of the three buttons on the trumpet, your child can play the delightful musical sounds of the trumpet, French horn, or tuba. The head of the brightly colored Caterpillar Trumpet squeaks when squeezed, and a slider makes a fun clicking sound when baby moves it up and down. One the side of the trumpet, there is an engaging real-world picture of a caterpillar to further your little one’s discovery. The Caterpillar Trumpet is sturdy and safe for little hands.
