Abstract: A toy truck having a crane arm, comprising multiple telescopic components to form a crane extension mechanism. The crane arm extension mechanism includes a crane arm that is capable of telescopically extending based on the air pressure manually provided to fill telescopic members of the crane arm. To telescopically extend the crane arm, a crank is rotated which causes an air pump to pump air into the crane arm. As the air pressure in the crane arm increases, the crane arm telescopically extends.

Abstract: A music playing device for symphonic compositions allows a user to selective locate one or more musical instrument playing pieces within an orchestral pit and to listen to the series of notes of those instruments placed into the pit. The additive and subtractive benefits of musical instruments are thus appreciated. The device comprises a main base and individual, preferably, three dimensional musical instruments as playing pieces. Multiple symphonic musical compositions are available to be played with only the notes of those instruments being heard if and when placed into the pit area.
