MILWAUKEE - Some kids ask for Legos, others a train. But Dustin Kruse, 4, of New Berlin, Wisc., wanted something extra special this Christmas -- a toilet.

Dustin Kruse loves toilets so much that it prompted one local company to grant the child's wish for a top-of-line, double-flusher.

"They did it right after his fourth birthday. Delivered, installed it, everything," said Michele Kruse on Newsradio 620 WTMJ's Wisconsin's Morning News.

Kruse said her son is so fascinated with toilets that he wanted to ask Santa for a particular type of Kohler toilet, a dual-flush brand that allows people to either make a full or a half flush.

According to the Journal Sentinel in Milwaukee, Dustin encountered his $380 porcelain dream during a trip to the Kohler Design Center where he was able to touch the high-end model.

"He flushed it," Michele Kruse told the Journal Sentinel, "and he's like, 'Mom wouldn't that be great if I could have this? Could you imagine all of the things I could do?' And then he's looking up in the air and he's thinking. He's like, 'I am asking Santa Claus for this.'"

Dustin's mom said she didn't want to flush away her son's hopes, so she wrote to Kohler, explaining her son's interest -- and Kohler obliged.

Michele Kruse called her son's fascination a mere interest and far from an obsession.

As she put it: "It's fun."
