 1. Field of Invention
 This invention relates to an animated musical alligator which features movement while playing music. When it plays songs, mouth movements occur in synchronization with the singing, as a result of its circuitry and mechanical operation system. In addition, the alligator produces realistic walking movements and up-and-down, as well as side-to-side head movements.
 2. Description of Prior Art
 Often, novelty items manufactured for the purpose of play or entertainment may produce music or include some movement by characters that the items may showcase. However, such products lack true entertainment value because their features are too predictable. In contrast, the animated musical alligator combines a variety of different functions to create an attractive and captivating novelty item that will appeal to individuals of all ages.
 The object of the animated musical alligator is to provide an original, amusing toy and novelty item for adults and children, alike. The advantages of the invention are its combination of entertaining functions. These functions operate by means of the alligator's circuitry and mechanical operation system:
 1) The alligator can play music and initiate mouth movements in synchronization with songs that it plays.
 2) The alligator produces realistic walking movements.
 3) The alligator can create head movements consisting of a swaying action from side to side, as well as an up-and-down action.
 This invention consists of an animated musical alligator designed to provide an interesting and unusual toy and novelty item for adults and children to enjoy. By means of its intriguing combination of functions, the alligator offers an especially attractive and unique type of entertainment. The invention can produce mouth movements in synchronization with the singing, as a result of its circuitry and mechanical operation system. In addition, the alligator produces realistic walking movements and up-and-down, as well as side-to-side head movements.

 Description of Preferred Embodiments and Operation of Invention
 IC 40 is an integrated circuit that creates sound signal output and movement signal output. It is driven by trigger circuit 42. I-1 is connected to an amplifier 44, producing sound through a speaker 26. I-2 is connected to driving circuit 48 to drive motor 9 so that mouth movements are produced in synchronization with the sound that is created. I-3 is connected to driving circuit 50 to drive motor 21, causing the alligator's leg movements. I-4 and I-5 are connected to driving circuit 52, activating motor 10 to cause the alligator's head to move up and down.
 (A) Mouth movements: When electrified, motor 9 rotates and decelerates through gears 8 and 7 to drive gear 6 and eccentric gear 4 to cause the alligator's upper jaw 1 to raise upward. At the same time, eccentric gear 4 drives lever 3 to turn around so that the alligator's lower jaw 2 moves downward. When power is cut off, twisting spring 5 pulls the upper jaw 1 and lower jaw 2 back to their original positions.
 (B) Leg and side-to-side head movements: When electrified, motor 21 decelerates through gears 19, 18, and 17 to drive eccentric gear 16 to rotate, so that lever 23 will move back and forth. This action, in turn, drives foreleg 15 and hind leg 24 to move forward. Since eccentric gear 16 is not symmetrical, the head sways from right to left as a result of the motion of eccentric gear 16.
 (C) Up-and-down head movements: When electrified, motor 10 rotates, decelerating through gears 11, 12, and 13. Since fan-shaped gear 14 is fixed, gear 13 turns around it, causing the alligator's head to raise up. When the music that the alligator plays has ended, motor 10 reverses to return the alligator's head to its original position.
 In conclusion, this invention is designed to create an unusual and amusing novelty item that is highly entertaining for adults and children, alike. The invention accomplishes this goal by means of its circuitry and mechanical system. The invention's integrated circuit, which creates sound signal and movement signal outputs, produces music through its amplifier and speaker. Additionally, the IC activates various motors, which trigger gears to create leg movements and side-to-side and up-and-down head movements. Finally, mouth movements are created in synchronization with the playing of songs.
