A toy comprising a stack of elements including at least first, second and third elements having a cord running therethrough. The cord is configurable between a taut state in which the stack is prevented from toppling, and a slack state in which the first, second and third elements are movable relative to one another to effect toppling of the stack. The first element comprises a stop configured to limit movement of the second element relative to the first element to a pre-determined range such that the stack is only partially toppled by movement of the second element through the pre-determined range, and movement of the first and/or third element is necessary for the stack to reach a fully-toppled state.
