Seems good at first - but a major flaw exists

As the pattern choices are random, usually the options only include one tile from the actual pattern...meaning regardless of the difficulty, you just need to pick the only animal thats in the pattern. A stupid flaw. So...want to complete the pattern...just pick the only animal that was actually in the original. Takes a kid about 3 mins to figure this out. Fix please.
