Singapore's town planners and local administrations like to decorate neighbourhoods with landscaping, statues etc. Also, foot reflexology walks (paths with small stones that one should walk barefoot to stimulate bloodflow etc) are quite common, as are fitness corners and such.
In this case, a complete set of statues representing the Chinese Zodiac has been placed alongside a storm drain with seats to rest and relax.
The cache location however does not overlook the statues, (there its predecessor kept getting muggled), so after (or before) finding it, do go and take a look at the Zodiac and find your sign and mention it in the logs.
By MRT to Bukit Batok, then take buses 77, 106, 852, 157 for one or two stops. Buses 77, 106 and 174 can also be taken here from the City (direction: Bukit Batok). 106 is also an option from Clementi MRT station. Other buses plying nearby: 963 from Woodlands or Harbour Front.
If you get hungry, there is food all around (hey, this *is* Singapore after all). There is a Kopitiam (coffee shop) with various local food varieties across the storm drain and road.
In the other direction, you will find American Food sold by a chain owned by a bald (Botak) man.. Further on, at Bukit Batok Central you will find more food option, outside and inside WestMall.
