When Mor'du is killed towards the end of the film he turns into a will o' the wisp and we realise that they are the spirits of the dead. During the credits a will o' the wisp appears over the credit "dedicated with love and gratitude to Steve Jobs, our partner, mentor and friend."
After the credits, the crow arrives to deliver all the wood carvings Merida bought.
The final credit is headed Production Babies and is followed by a list of 68 given names (including a set of twins) of children born to members of the production team during filming.
