Little creature in the garden

In Brunei you get surprise animal visits in your garden every now and then. We had a big monitor lizard at the previous house, some snakes (not poisonous ones like next door tho), monkeys and pretty birds. Our recent addition is a squirrel. He lives in the tree behind Oliver's house (I think) and plays in our garden.

He (or she?) is always running up and down the trees or fences. Today he got more adventurous and spent a good 15min in the garden while Matthew and I chased him with our camera. He checked out our front garden, sat on our outside furniture, ate an acorn, and played in Oliver's house. Unfortunately Oliver was having his afternoon nap and missed out on the excitement.
