A little girl in the U.K. has lost her stuffed rabbit -- and she needs your help to find him.

The Jellycat stuffed animal goes by the name of Mr. Rabbit and belongs to his best friend, 3-year-old Ruby. Mom Zoe Stewart wrote on her personal blog that the family left Flat Iron Steak restaurant in London with the bunny on the night of November 16, but sometime later that evening, the toy disappeared.

Once mom realized that Mr. Rabbit was missing, she turned to the online community for help.

"Now, I know what your [sic] thinking… It’s just a teddy, replace it and she’ll never know," mom wrote. But "he was there when she was in hospital, he was there when she had chicken pox, her first tooth, the first time she fell and skint her knee or bumped her head. He’s seen it all."

"His neck has no stuffing left from being hugged so much so flops to one side and his ears smell like Olbas Oil," she added, by way of further description.

She said that Ruby has had the stuffed toy since right after she was born -- and wrote on Facebook that the little girl has been crying herself to sleep.

Zoe has used social media to try to get the word out about her daughter's beloved friend.

On Twitter:

And on a Facebook page with more than 2,000 fans:

The stuffed animal is even listed in the Teddy Bear Cuddly Toy Lost and Found.

Some Facebook commenters have offered their own stuffed bunnies, but Zoe and her daughter Ruby aren't giving up on locating the real thing.

“I think the whole of the U.K. is looking for him,” Stewart told ABC. Hopefully, not in vain.

    This photo is from September 2010. I had just shaved my head for St. Baldricks in honor of my son Levi, pictured. He was diagnosed with stage 4 brain cancer (Medulloblastoma) in 2004 when he was only four. Surgery to remove the tumor left him mute, paralyzed and incontinent. He relearned all his life skills while undergoing multiple surgeries, chemotherapy and intense radiation. He is my hero.

Her expression was not posed, I had wanted her to look at the camera but he did a little sigh in his sleep and she said “aww” and turned her head towards him and closed her eyes. I teared up as I clicked the shutter, so magical.

    The attached photo is of my 3-year-old twins, Petra and Ivan. They're both on the autism spectrum, but Ivan's powers of speech are far more advanced than Petra's, and on some level he seems to know this. He makes sure she's not overlooked when we're doing family things, and occasionally takes her hand to walk with her when we're out. If she pulls away he reaches out to grab her hand again, to make sure she doesn't get left behind!

  • This picture was taken one Sunday afternoon when we were leaving Church. My daughter had been getting upset during the Mass because she was missing her Auntie who had passed away earlier that year from cancer. She told her brother how she was feeling as they were leaving. He put his arm around her, hugged her and kissed her forehead telling her that everthing was going to be alright. As they walked the remainder of the way to our car, they held hands. It was so precious. They did this all on their own. This is the true definition of sibling love at it's finest! I just walked quietly behind soaking it all in. (And of course taking a picture like any good mom would :)

  • Angela and Dad

    This image was taken moments after mom, who had been looking on, had *that moment* - that moment when you realize your entire world has changed – that moment as a new mother that takes your breath away. Her eyes filled with tears of overwhelming joy and love and got both of us, the dna photographers, and the daddy to well up – the only one not crying was the 8 day old little angel in daddy’s arms.
