A toy assembly, comprising: a toy assembly housing; and an extensible object inside the toy assembly housing, wherein the extensible object includes a base, a first extension member that is movable relative to the base between a retracted position for the first extension member and an extended position for the first extension member, and a second extension member that is movable relative to the first extension member between a retracted position for the second extension member and an extended position for the second extension member; an extension mechanism that is operable to drive the first extension member towards the extended position for the first extension member and to drive the second extension member towards the extended position for the second extension member, and an extension mechanism power source operatively connected to the extension mechanism to drive the extension mechanism, characterized in that: the extension mechanism is operatively connected to the second extension member via a lost motion connection having a selected amount of lost motion, wherein, when the extensible object is in a home position, driving of the extension mechanism by the extension mechanism power source drives the first extension member towards the extended position for the first extension member to break or open the toy assembly housing to expose the extensible object while consuming at least a portion of the lost motion in the lost motion connection so as to prevent movement of the second extension member towards the extended position for the second extension member, while breaking or opening the toy assembly housing, wherein, upon consuming an entirety of the lost motion in the lost motion connection, further driving of the extension mechanism by the extension mechanism power source drives both the first and second extension members (28, 30) towards the extended positions for the first and second extension members (28, 30). a toy assembly housing; and an extensible object inside the toy assembly housing, wherein the extensible object includes a base, a first extension member that is movable relative to the base between a retracted position for the first extension member and an extended position for the first extension member, and a second extension member that is movable relative to the first extension member between a retracted position for the second extension member and an extended position for the second extension member; an extension mechanism that is operable to drive the first extension member towards the extended position for the first extension member and to drive the second extension member towards the extended position for the second extension member, and an extension mechanism power source operatively connected to the extension mechanism to drive the extension mechanism, characterized in that: the extension mechanism is operatively connected to the second extension member via a lost motion connection having a selected amount of lost motion, wherein, when the extensible object is in a home position, driving of the extension mechanism by the extension mechanism power source drives the first extension member towards the extended position for the first extension member to break or open the toy assembly housing to expose the extensible object while consuming at least a portion of the lost motion in the lost motion connection so as to prevent movement of the second extension member towards the extended position for the second extension member, while breaking or opening the toy assembly housing, wherein, upon consuming an entirety of the lost motion in the lost motion connection, further driving of the extension mechanism by the extension mechanism power source drives both the first and second extension members (28, 30) towards the extended positions for the first and second extension members (28, 30). the extension mechanism is operatively connected to the second extension member via a lost motion connection having a selected amount of lost motion, wherein, when the extensible object is in a home position, driving of the extension mechanism by the extension mechanism power source drives the first extension member towards the extended position for the first extension member to break or open the toy assembly housing to expose the extensible object while consuming at least a portion of the lost motion in the lost motion connection so as to prevent movement of the second extension member towards the extended position for the second extension member, while breaking or opening the toy assembly housing, wherein, upon consuming an entirety of the lost motion in the lost motion connection, further driving of the extension mechanism by the extension mechanism power source drives both the first and second extension members (28, 30) towards the extended positions for the first and second extension members (28, 30).
