A device configured to be detachably coupled to a toy is described. The device comprises a housing and a wing assembly coupled to the housing. The wing assembly comprises at least one wing configured to rotate about a rotational axis in a flapping motion, and a gear assembly configured to cause rotation of the at least one wing. The device further comprises at least one coupling means configured to engage with a magnetic strip of the toy, thereby facilitating a detachable coupling of the device with the toy.
