Here are some toy trends that will be highlighted at the American International Toy Fair, which officially starts Sunday. Most of the toys showcased will be in stores later this year.

• ROCK GUITAR: Does your child want to be the next Mick Jagger? The nation's toy makers are tapping into children's interest in rock with toy guitars to finetune their jamming skills. Mattel Inc.'s Fisher-Price brand has ''I can Play Guitar,'' priced at $99, which plugs into a TV and features color-coded finger position buttons. Hasbro Inc. is unveiling Power Tour Electric Guitar, which is priced at $69.99 and features a strum bar, touch sensors and multicolored lights.

Meanwhile, Zizzle LLC is offering a Rockerz Jammin' Guitar, priced at $7.99., as part of a collection of musical instruments tied to the popular Disney Channel movie ''High School Musical.'' It allows kids to add their own sound effects with a push of the button.

• UNLOCKING THE INTERNET: Toy companies want to be where children are: the Internet. A number of companies are focusing on new game systems that interact with cyberspace, while Mattel and Hasbro are going a bit further, offering environments that allow kids to play games without venturing into other areas online.

Mattel's Fisher-Price brand is showcasing Easy-Link Internet Launchpad, priced at $29.99, which parents connect to their computer to allow kids to safely visit preschool appropriate Web sites. Children can plug their favorite character figures into the launch pad and be taken directly to the game section of that character's Web site.

Hasbro's Tiger Games division is marketing Net Jet, a game system that offers preteens 40 online games in an environment without banners and popup ads. The system, priced at $24.99, has a controller and game keys, which unlock the content library.

• TOYS GO HOLLYWOOD: The toy industry is poised to benefit from a number of expected blockbuster movies to be released later this year.

Hasbro will supply toys for three of the year's widely anticipated films: ''Transformers,'' based on its 23-year-old toy brand, ''Spider-Man 3'' and ''Fantastic Four: Rise of the Silver Surfer.'' Spiderman items include a Deluxe Spinning Web Blaster, which creates spiral webs with special fluid, and Spider Spud, inspired by the iconic Mr. Potato Head. Hasbro is also coming out with a voice changing helmet and assorted action figures for ''Transformers'' and action figures and role-playing accessories for ''Fantastic Four.''

• T.M.X. FRANCHISE EXPANDS: Mattel Inc.'s Fisher-Price is hoping to replicate the success of T.M.X. Elmo by expanding the technology to his other friends: Cookie Monster and Ernie.

The toy company will be shipping smaller versions of the two Sesame Street characters, marketed under T.M.X. Friends, to stores in October, according to Gina Sirard, vice president of marketing for Fisher-Price. With these new versions, which will sell for $29.99 each, the movement and squeals will grow more pronounced with two successive tickles. T.M.X. Elmo sells for $39.99 and has three levels of laughter.

T.M.X. Elmo was one of last holiday season's biggest hits; toy consultant Chris Byrne estimated that Fisher-Price sold close to two million units last year. Sirard wouldn't say how many have been sold, but said the company continues to manufacture and ship more.
