Eau de Peanut Butter

Thanks to advances in shampoo science, it's possible now for a person's hair to smell like kiwi fruit or coconut or even chocolate milk. If that seems strange -- unnatural -- consider the seabird with the bill that smells like a tangerine.

That's the Parakeet Auklet, a chubby little Arctic species. Another oddly scented creature is the Mountain Yellow-legged Frog, which some people think smells like freshly chopped garlic. The Western Spadefoot toad, meanwhile, smells a lot like peanut butter.

As for plants, the Ponderosa Pine is often described as smelling like pineapple. And the sunny side of a Jeffrey Pine smells like butterscotch, while the scent of its crushed twigs has been likened to lemons, vanilla, and violets.
