NEW YORK ( TheStreet) -- Mattel ( MAT - Get Report) reported a first-quarter loss that missed Wall Street estimates and highlighted the company's Barbie problem.

The news sent shares of Mattel down 2% to $37.05 in recent trading. The stock is down 22% so far this year.

Among its core brands, Barbie suffered the biggest sales drop -- down 14% in the period. She may be the muse of the company, but was barely mentioned on the company's conference call this morning. For the quarter, net sales for Mattel were $946.2 million, down 5% from $995.6 million last year.

Sales of the doll and its play-sets have been sliding for quite some time. Although children are gravitating more toward technological toys, such as Apple ( AAPL - Get Report) iPads and LeapFrog ( LEAP) Leappads, there is still something to say about imaginative play. Children, mainly young girls, still do enjoy playing with dolls.

Mattel says gross sales worldwide for "Other Girls" brands rose 4%, driven by the Disney Princess -- especially from the the blockbuster Disney ( DIS) movie Frozen and television show Sofia the First. It also says the brand, Ever After High, helped offset slower sales of Monster High products.

Mattel should continue to shine a brighter light on its American Girl brand -- including the new "Girl of the Year," Isabelle. First-quarter gross sales for American Girl continue to grow, up 5% versus the prior year, raking in almost $106 million.

With more households tightening their belts, kids may be playing with more hand-me-down Barbies. For a special treat, a mom may buy a new bargain Barbie that sells for just $3 at Walmart ( WMT - Get Report).

As the economy continues to recover, 22 million Americans are still unemployed or under-employed. In a statement, Mattel CEO Bryan G. Stockton said the company is facing a "challenging retail environment."

Plus, new parents may be using more second-hand baby gear, passed down from friends or family. First-quarter worldwide gross sales for Fisher-Price Brands fell 6% to $271.4 million from the prior year.

Mattel Chief Financial Officer Kevin Farr says the company "still has a lot more work to do."

It plans to expand its entertainment properties, boost international sales and focus more on its core brands.
