Tickle me Cookie, tiny penguin goes gaga over belly rubs

What happens when a pipsqueak penguin gets tickled?

Brace yourself. Cookie, a miniature breed of penguin and the mascot at the Cincinnati Zoo's birdhouse, goes positively wild. 

No more than 12 inches tall, this litttle guy's giggle fit has become an internet sensation, drawing half-a-million views.
