So your kid wants a dog. You think, maybe a cat. a fish? If you’re still unsure about the added responsibility, Think Geek has an option. Let them enjoy a goldfish without having to worry about feeding it. The Electronic Goldfish in a Bowl needs just three batteries and water in its bowl. Tap the top and the fishy “swims” around just like the real thing. Except you’ll never have come home to him floating on his back.
