There is mechanism provided for movably mounting the legs relative to said body portion. A gear train is operated by a motor to move the legs relative to the body portion in a downwardly direction to compress the coiled tail spring and then release the legs and body portion to set up a harmonic motion of the body and spring tail. ## Claims ### Claim 1 A toy character comprising a body portion having a leg assembly and a spring tail portion connected to said leg assembly, a motor secured to said body portion, a switch operated powered motor controller means for operating said motor, a gear train driven by said motor, a gear rack secured to said leg assembly, means including springs for movably mounting said leg assembly relative to said body portion, said gear train including a drive pinion having a partial tooth portion for engagement and disengagement with said rack whereby when the pinion is in engagement with the rack the legs will move downward against the action of the springs and when moved out of engagement with the rack the character will be moved upward by the spring tail. ### Claim 2 (depends on 1) A toy character as set forth in claim 1 in which the spring tail portion is in the form of a coiled spring. ### Claim 3 (depends on 2) A toy character as set forth in claim 2 in which the leg assembly includes two legs and means for connecting the spring tail to one of said legs. ### Claim 4 (depends on 3) A toy character as set forth in claim 3 in which the means for movably connecting at least one of said legs to said body portion includes a slot defined by one of said legs and a fastener means extending through said slot into said body whereby the leg assembly can move relative to said body portion. ### Claim 5 (depends on 4) A toy character as set forth in claim 4 in which there is a compression spring in said slot acting against the fastener means whereby when the legs are free to move in an upward direction the spring in said slot will aid in said movement. ### Claim 6 (depends on 4) A toy character as set forth in claim 4 in which there is an extension spring interconnecting the leg assembly and said body portion whereby when the leg assembly is free to move upward the extension spring will aid in said movement. ### Claim 7 A toy character comprising a body portion having a pair of legs, a spring tail connected to one of said legs, means connecting said legs together, means for movably mounting the legs relative to said body portion, a motor secured to said body portion, a switch operated powered motor controller means for operating said motor, a gear train driven by said motor, a gear rack secured to one of said legs, said gear train including a drive pinion having a partial tooth portion for engagement and disengagement with said rack whereby when the pinion is in engagement with the rack the legs will be moved downward against the action of the spring tail and when moved out of engagement with the rack the character will be moved upward by the spring tail. ### Claim 8 (depends on 7) A toy character as set forth in claim 7 in which the tail comprises a coil spring. ### Claim 9 (depends on 8) A toy character as set forth in claim 8 in which the means for movably connecting the legs relative to the body includes at least one of the legs defining a slot and fastener means extending through said slot into the body portion. ### Claim 10 (depends on 8) A toy character as set forth in claim 8 in which there is an extension spring interconnecting the legs and the body portion whereby when the legs are free to move upward the extension spring will aid in said movement. ### Claim 11 (depends on 8) A toy character as set forth in claim 8 in which there is located in said slot a compression spring acting against said fastener whereby during the downward action of said body the tail spring and the springs in said slot are compressed and when the rack is disengaged from said pinion the springs create the upward movement of said body portion. ### Claim 12 (depends on 11) A toy character as set forth in claim 11 in which each of said legs contain the slot and spring assembly to move the legs and body upward when the pinion is disengaged from said rack.
