Singa the Courtesy Lion may have "resigned" to much online fanfare last week, but more recently, Water Wally, the Public Utilities Board's water droplet mascot, has been making his own waves online.

Entitled 'The Water Wally Shower Dance', the clip shows Water Wally dancing to a rap, reminding children and adults to keep their showers under five minutes.

The video drew flak for a scene where Water Wally walks in as a boy was showering, with some netizens making comments that it was inappropriate and comparing Wally to a "paedophile".

To date, students from 28 primary schools have learnt the Water Wally Shower Dance as part of PUB's water conservation initiative "Time To Save". About 29 per cent of an average family's monthly water consumption is used in the shower, the agency added.

Along with the dance, students were given a timer and an activity booklet to track their shower duration for the week. The initiative has seen students from each school saving an average of 88,100 litres of water per week, said PUB. id.

Besides primary school children, PUB hoped to reach out to an online audience with its Youtube video.
