Toys are no longer meant only for children - they are treasured by adults too. In a spring/summer preview hosted by toy manufacturer Mattel recently, a new collection of children's favourites, including Barbie, Kelly and Hot Wheels, was introduced. There were also action figures, playsets and accessories from Robots, the 20th Century Fox movie which is scheduled to hit Hong Kong cinemas in July. The three-dimensional animation features a battle between good and evil as the hero - the brilliant but naive Rodney Copperbottom - pursues his dream of working alongside famous inventor Mr Big Weld in a world inhabited solely by mechanical beings. With voiceovers by stars including Ewan McGregor, Robin Williams, Halle Berry and Mel Brooks, Robots is expected to be a summer blockbuster. A pack contains two 8.8 centimetre-high characters, such as Rodney and his friends Fender, Piper Pinwheeler, Diesel Springer, Lug and Crank Casey, as well as his evil nemesis Ratchet, with interchangeable snap-on limbs and stylish accessories. For more serious collectors, there are larger figures (17.7cm) with die-cast feet and body parts that can be twisted to form different poses. If you want to play a robot, try the Rodney-like Roboots which run, stomp and kick with noise. 'The Robots series has been developed for both kids and adults,' said Cheok Ching-won, marketing manager of Mattel's boys' line in East Asia. Mattel will launch more than 100 new models of its most popular toy last year, Hot Wheels. Among the cars to look out for are three X-Essence models - Drop Tops, X-Ray-Cers and Torpedoes - as well as Realistixs, Track Aces, Segment and Treasure Hunt. Hot Wheels AcceleRacers will see the cars and their drivers battle to save the world. A four-hour animation featuring the racing scenes will be broadcast on local television later this year. Meanwhile, Barbie will focus on fashion this year. The Fashion Fever Barbie features at least 20 new looks, cool accessories and mix 'n' match items. Children and adults can create their own versions. Barbie is a funky performer in the Idol Barbie series, a veterinarian in Pet Doctor Barbie, and a surfer or horse rider in California Girl. In the My Scene series, Barbie and her friends Madison, Nolee, Chelsea and Delancey go to Miami for fun and relaxation. Lizzie McGuire star Hilary Duff will appear in the Barbie commercials for the new season. 'Barbie introduces girls to many different things like fashion and make-up, and these are what they really like,' said Angeline Marina David, Mattel's regional marketing communications manager. 'The doll has changed life for many of us.'
