When Dodo arrived at Samboja Lestari, he was the youngest orangutan in the baby group.
He often played by himself because the older orangutans were much better at climbing and much stronger.
Now aged 5, his climbing skills are improving - he loves playing on a net made of old tyres. His boisterous, cheeky character shines through even when he's feeling unwell.
Dodo is gaining self confidence and working on his foraging and nest building skills.
