These are the only two pictures I've ever seen of a "weedwhacker" bubble blower. It looks like a possible Fisher Price toy, but I don't know. The words on it are simply "Bubble Whacker."
Directions say to push the yellow button and bubbles will come out. The trigger switch is used to operate the item. It also has an air vent on the bottom and a soap filler/bubble discharge on the side. The weedwacker takes 2 "C" batteries.
