Yup and that the animal the boys and I wanted to see the most. The silver back was hard to see that day. Mostly stayed in his cave. Don't blame him as you said all those noisy excited kids.
Ah yes I heard about Shabani, he used to be on the news a lot. Along with Shan Shan the panda.
I must say through, Ueno zoo is massive. Could spend the entire day there , which we kinda did and not see all the animals. Many were on their day off though 😝
