If you were wondering how you could brighten your boring life without looking for an interesting friend bring home Tengu and call him your buddy. Tengu is an intelligent USB doll who detects the slightest sound and mimes or mimics it. If you happen to laugh or sing, he laughs and sings back in a manner that would make you smile, for a change.

Nevertheless, I have my own evil ideas. I could shriek and scream till Tengu does the same thing so that the neighbors would know the house is haunted and that they should not venture or trespass into my territory.

All you would need to do is plug Tengu into your computer, and when there is no noise he will fall asleep. When you blow on his face, he wakes up and he joins you when you play music. Just blow again on the mic to change his facial expressions. At £19.99, he must be the cheapest friend you could bring home and probably the nicest too.
