PHOENIX -- A 5-year-old Chandler girl who collected slippers for sick children at Phoenix Children's Hospital delivered them on Monday afternoon.
Lilly Zienkewicz dropped off more than 1,500 pairs of slippers.
"She's always been compassionate person," said Lori Zienkewicz, Lilly's mother. "She's very shy she kind of doesn't like the spotlight so she'll be a behind the scenes coordinator."
The idea came to Lilly when she was in the hospital recently with a rare blood disorder.
That's where Lilly quickly became popular for her Hello Kitty slippers.
When Lilly got home she decided she wanted to give slippers to all of her friends on the seventh floor, in honor of her best friend Hannah Huckfeldt.
She knew Hannah since she was born, but she died of cancer last year.
Today is the first anniversary of her death.
"Lilly even sometimes references my angel in heaven," said Shelly Huckfeldt, talking about daughter Hannah. "I think she is definitely looking down on her proudly for what she's doing and continuing her memory on in an inspirational way."
Lilly originally thought if she could get 100 pairs of slippers, her drive would be a success and Hannah would be proud of that.
But with help from family, Facebook and school friends, Lilly has collected close to 1,600 pairs of slippers in her family's basement.
"Word of mouth spread," said Lori Zienkewicz, Lilly's mother. "We got slippers from all over the country."
