In a small warehouse Liliana Perez stores papier-mâché creations, some up to six feet tall and covered in crepe paper of every hue imaginable. Each week Perez says she moves about 200 pi?atas, including bright-green dragons, coffee-color horses, jolly clowns, and even butterflies. Drum-shape pi?atas are stacked to the ceiling; they go for wholesale prices to party-supply stores. "I can make a pi?ata for any occasion," Perez boasts. A few years ago Metrozoo asked Perez to make five life-size animals for display. During the Christmas season, she produces Santa Clauses. And some corporations have ordered their company logos in the form of pi?atas. Perez even made a perfectly round sun with tentaclelike rays that brightened up a little boy's winter birthday party. When the children pulled on its orange, yellow, and red strings, a shower of sweets poured down on them. Prices for Perez's pi?atas range from $12 to $250.
