We were at a kids party last week and someone brought this awesome balloon that simply floats around the room but can be remote-controlled by a little orange box easy enough for a 3-year-old to move it around the room.
You can pick up a clown fish or a shark from Amazon: Air Swimmers Remote Control Flying Shark
