If you need to feel like a kid again...
go to the Original Tote shop, level 3 Raffles City shopping centre.

Their toys are soo good and creative that you'd want one too. I bought one caterpillar for my nephew and just in case the other kids got jealous, bought them a bubble blower each. Remember playing that? It bring back memories when I played it at the office just now. And judging from the way some colleagues blow, we know who don't have a childhood. Hah!
