Two global iconic characters, Blue—the beloved puppy from the landmark Nickelodeon preschool series “Blue’s Clues”—and Sanrio’s Hello Kitty appeared “in person” on March 8 in Sanrio’s New York Times Square flagship store.

The event celebrated the co-licensing deal between Nickelodeon and Sanrio. Both Hello Kitty and Blue’s Clues costumed characters met with fans and were available for photos as the store unveiled a specially designed product line created specifically for tweens and young adults.

Products available in the limited-edition run include stationery items as well as collector items such as chopsticks, mascot straps, rubber key covers, sandals, bandannas, umbrellas, lunch boxes, compact mirrors, handkerchiefs, and face towels.

The merchandise is currently available in New York, San Francisco, and Honolulu, and will be followed by limited-edition product launches in Los Angeles, Chicago, Orlando, Miami, and Las Vegas in the coming weeks.
