Now, here's an update.
After a lot of digging, I managed to find more info on the show!
Apparently, the show was actually produced entirely in Australia rather than being an American-Canadian-Singaporean production, and was animated by Yoram Gross EM.TV rather than being produced by Nerd Corps, March Entertainment, and Scrawl.
The series actually utilized outline-less 2D animation and it also used live-action segments in between the episodes for the CBBC airings.
If I remember correctly, this was shown as part of Dick and Dom in Da Bungalow, and Scandrew and Charlotte the Pixls would sometimes call Dick and Dom on their phones.
Whoa, outline-less 2D animation? That sounds kinda experimental for its time! Was it like the stuff that Cartoon Network experimented with? I love me some obscure animation techniques. Gotta find some clips now!
