Rachael knows a thing or two about cooking for humans, but what will happen when she has to prepare lunch for two of her biggest eaters - polar bears! If that isn't enough pressure, she has to compete against a polar bear expert from the Central Park Zoo! Whose creation will the polar bears chose?

The Competition

Gus - He weighs 950 lbs, but can reach 1100 lbs in the winter. He uses his strength over his smarts.

Ida - She weighs 675 lbs. She is very smart and usually reaches the food first.

Armed with a degree in animal science, veteran zookeeper Rich Camili knows the biology, anatomy, behavior and personality of the bears. He works mainly in the polar section with polar bears, sea lions and penguins. In fact, he can pick out each of the zoo's 60 penguins by name! Rach has got her work cut out for her!

Rach works up a sweat creating her masterpiece for Gus and Ida: tilapia on a block of ice garnished with her special watermelon and green bell pepper salsa. But her hard work pays off - the bears gobble up her meal over the zookeeper's!

Since Gus and Ida are too big to fit in a taxi, Rachael invites Pete and Penny (two Magellanic penguins from Seaworld) to her studio home.

Betcha didn't know these cool penguin facts:

• Cartoons and films often depict penguins and polar bears together, but polar bears only are found north of the Equator, and penguins only south of the Equator. These two species would not be found anywhere near one another.

• Penny looks like she's sneezing, but she's actually excreting salt from her salt glands. Since penguins swim in salt water, they need to do this in order to stay hydrated. It's like her own personal salt shaker!

• The emperor penguin is the largest penguin species standing 44 inches tall and weighing up to 90 pounds. The fairy penguin is the smallest, measuring up to 16 inches tall and weighing less than 5 pounds.

• Adult penguins are countershaded, which means they are dark on the dorsal side (top/back) and light on the ventral side (bottom/front). This helps conceal swimming penguins from predators such as killer whales, sharks or leopard seals. When viewed from above, the dark dorsal side blends in with the darker ocean depths. When viewed from beneath, the light ventral side blends in with the lighter surface of the sea.
