Get ready for a “Frozen” Halloween. No, not weather-wise. Millions of children are expected to dress up as Queen Elsa, Princess Anna and snowman Olaf from the 2013 Disney movie come Oct. 31.

About 2.6 million children plan to dress up as characters from “Frozen,” the Disney film released last year featuring Anna, Elsa and snowman Olaf. “Frozen” also made the list of top kids’ costume searches on Google, Yahoo and Amazon. The trend marks a departure from Halloween 2013, which centered around traditional, generic characters like animals and fairies, according to the National Retail Federation.

“It’s clear people love to get creative with costumes, looking for inspiration from pop culture and politics to history, and even the make-believe and fantasy world,” Prosper Insights Principal Analyst Pam Goodfellow told the NRF in a news release. In total, people will spend $1.1 billion on children’s costumes this year.

Superheroes always make a strong showing on Oct. 31. This year, 1.8 million kids will dress as Teenage Mutant Ninja Turtles, according to the NRF. Yahoo searches for “ninja turtle costume” shot up 5,225 percent between Oct. 11 and Oct. 18. About 2.6 million kids will be Spider-Man this year, which incidentally was the top children’s costume in 2004, according to Better Homes and Gardens. In 1994, children wanted to be Power Rangers.

“Despicable Me” minions carried over from last year to this one, as did princesses. In 2012, the top kids’ costumes included Monster High characters – which made Yahoo’s most-searched list this year, too – and Angry Birds.

Amazon also has many searches for Minnie Mouse costumes and Skylanders, a group of Activision video game characters, that came in at No. 10 on Yahoo’s kids’ costume list. As for non-brand-name getups, the NRF found that witches and pirates will abound, as well.
