I don't understand "It's such an expressive nose!" in the following paragraph. Please explain the meaning.
------- the following ---------
Michelangelo looked at a block of marble and saw a man. Elffers looks at a lemon and sees a pig. Growing up in Holland, he was taught to clear his plate; playing with food was forbidden. As an adult, the artist visited Japan, where, he recalls, food was �almost too beautiful, and without humor. Food should be a joy.� With his edible produce sculptures, Elffers hopes to share that joy. �If you give people permission to see the pig in the lemon, they will forever see animals in fruit or vegetables,� he says. �Americans carve pumpkins but they never use the stem. It�s such an expressive nose!� He urges pumpkin buyers to create their own zoos this Halloween. Elffers says, �Shop with an open mind.�

He's suggesting that the stem of a pumpkin can be used as a "nose" when carving pumpkins.
Pumpkins are hollowed out and carved into scary faces at Halloween and illuminated by a lighted candle or electric light, from the inside.
