Bear Manager Kelly Donithan said:
"Bears love the hessian sacks: they destroy them, rip them apart, play tug-of-war, use them for bedding, sleep with them, wear them – really! We often see the bears wearing the sacks on their heads or around their necks.
"Jigsaw is a very playful bear, and it's anyone's guess what he's up to when he picks up an enrichment item in the enclosure. It could be a number of things, but I bet he's just keeping it close by until he decides what to do with it!"
