By day, Christian McCulloch teaches nursery school. In the evenings, he is the English language adviser at the Bank of China.
But on weekends, faster than a speeding tadpole, he turns into 'Frog' - director of traffic at the Discovery Bay International School Internet site, Frog's Pond.
Frog, and his friends Toad, Herman the iguana and Fatty Piecrust the terrapin, keep things hopping on the child-centred site, which Mr McCulloch believes was the first primary school-sponsored one of its kind in Hong Kong. The focus is on fun and education.
'I think of it as eye candy - lots of visual presents, trivia, artwork, all kid-oriented,' Mr McCulloch said.
But behind the 'eye candy' are serious bites of education - environmental tips, some geography and language-enhancing children's reading.
For the three and four-year-olds of his Circus Nursery class, it is a chance to see themselves - and wave to overseas family - on the Net.
