I am planning to fly to SG during holiday in April. Beside of Universal, is there any activity place that suit for 3 years old girl?

I just visited Singapore few days back with my 2 yr old nephew, so I can definitely make some recommendations. He loved Singapore Zoo, Jurong Bird park (as you can see in the pic), and SEA aquarium. Also, most of these places have excellent water parks for kids to play so carry her swim wear along. Have fun you guys!!!
