Sprout the Orangutan is obsessed with playing with her sheet around her enclosure.

This clip, filmed October 25 in Dudley Zoo, shows the orangutan chewing the sheet before finally putting it on and pretending she’s a ghost.

The filmers, at her habitat at the Dudley Zoo in the West Midlands, said: “She's making some alteration and moves to a more comfortable position and continues her modification of the sheet there. When it looks like she's done, she puts it over her body and wraps it all around her. Just maybe some eye holes missing little sweet Sprout and then you're ready for Halloween!”
