Orangutan super mum Jazz has been looking after her grandson Joe, her daughter's son, since birth. There's a layer of ice on the logs, and Jazz is making the most of it, scraping some off the log. Joe’s little face pops up under Jazz’s arm, excitedly nibbling on the icy treat. All you can eat ice buffet! In the background, the gibbons' song fills the air, adding to the serene atmosphere of the cold, crisp day.

Down below, Jim, Jazz’s biological son, is more independent despite being only 28 days older. Djimat, the dad, is scraping off the ice with his teeth, before manoeuvring his large frame over the strap. Orangutan Sprout is holding tight to the icy log, using her lips to form little ice balls, scraping off more as she just can’t get enough. Jim looks as adorable as ever, licking the ice off his finger with a cheeky smile.
