Abstract: An inflatable member sits on a motor vehicle seat and can be seen from outside through a vehicle window. The inflatable member is in the form of a simulated living creature. An electrically powered air pump is provided for inflating the inflatable member. A switch, under operator control, is provided for activating the air pump. An electrically powered device is provided for emitting sound, and, under operator control, a switch is provided for activating the sound-emitting device. The air pump and the sound-emitting device include a plug which is adapted to fit into a cigarette lighter in a motor vehicle. The sound-emitting device includes recorded-sound media, such as a cassette tape, a cassette player, and a speaker. The speaker is housed in the inflatable member, and the cassette tape player is housed in a box separate from the inflatable member. More specifically, the box houses the air pump, the cassette player, and the operator-controlled switches for the air pump and the cassette player.
