For the DOLL FUNERAL . And they even ask Little Bear 's mom for a box for the funeral and the mom looks at them like " WTF YOU KILLED YOUR DOLL ? HOW DO YOU EVEN DO THAT , " but she goes along with it 'cause it 's Emily 's doll and if Emily says it 's dead , the doll is dead . Grown ups always try to do that whole " Oh look , she 's magically all better , " thing but kids never fall for it .

Why did Emily 's doll die ?
Emily was done playing with this doll and wanted something else to play with .
