WHITE hot “Pokemon” is suddenly in danger of cooling off – thanks to Disney’s “The Weekenders.”

For the first time in more than a year, the Japanese-made cartoon placed second among the prized two-to-11-year old kids demographic in the Saturday-morning broadcast ratings race, losing the top spot to ABC’s “The Weekenders.”

Until April 29, “Pokemon” had been No. 1 for an impressive 54 weeks (on cable, Nickelodeon rules Saturdays – easily beating the networks – with shows like “Rugrats” and “SpongeBob SquarePants.”)

“I’m stunned,” said “Weekenders” creator Doug Langsdale. “I’ve never had a No. 1 show before.”

“Weekenders” is loosely based on Langsdale’s experiences as a 12-year-old. It follows the adventures of four kids living in Southern California on a weekly quest for the ultimate weekend.

Episodes have revolved around themes ranging from preparing for competitive sports to mastering the latest dance/music craze to coping with the comic anxiety of attending a party or surviving a first “crush.”

“Its about stuff that matters to kids around that age,” Langsdale said.

“It’s also about stuff that matters to everyone,” he quickly adds. “I always think that kids have largely the same concerns as adults except for, like, taxes.”

For those who live in a vacuum, “Pokemon” is a Japanese cartoon, dubbed in English, that revolves around a race of monsters who possess a variety of powers and weaknesses – and can be trained as harmless pets or fearless fighters.

The hero of the Pokemon story is a 10-year-old boy named Ash, who is on a quest to collect as many Pokemon as possible. His sidekick – a Pokemon character and star of the show – is Pikachu, a cute “electric mouse” who can shock his enemies.

The show – which the WB airs at least twice, six days a week – along with two blockbuster movies (one set to open this summer) is supported by a wide variety of merchandise ranging from trading cards to electronic games that still sell like hot cakes.

Last November, during the peak of “Pokemon” fever, the publically traded shares of 4 Kids Entertainment – the company that holds the U.S. license for “Pokemon” merchandise – traded for as much as $93.25. Yesterday it closed at around $23.

Disney officials say that “for now,” there are no similar mega-merchandise plans for “Weekenders.”
