A 4-year-old girl in Tennessee is on the search for a Build-A-Bear accidentally donated to Goodwill.

The tie-dyed stuffed animal is deeply sentimental, holding a recording of her dead mother's heartbeat, according to a note posted to Facebook.

The bear is the only thing the little girl has left that belonged to her mother, according to the note. She's asking that if anyone has seen it, they return it to the Goodwill in Tazewell, Tennessee.

Build-A-Bear stuffed animals, some of which have the ability to record sounds, are sometimes used to memorialize lost ones.

In 2021, nurses at a Texas hospital gifted the three kids of a woman who died from COVID-19 Build-A-Bears containing a recording of their mother's heartbeat, which was captured on an EKG machine before she passed away, a local television station in San Antonio, reported.
