I discovered these links after the webcomics in question advertised on the Transformers Wiki:
The Dreamland Chronicles - Not a gag-a-day comic, but one ongoing story, all rendered in movie-quality CGI. The Dreamland Chronicles tells the story of Alex, who suddenly finds himself dreaming of the same fantasy world he dreamed of as a young child and has to deal with encountering the same characters he knew long ago, only grown up.
Weesh - and at the other end of the spectrum, Weesh, which is a gag-a-day strip (or at least every few days) and with a clean, simple drawing style. Three kids have a strange animal named Weesh, who has the power to grant wishes, so long as he gets enough licorice.
Both comics are family-friendly.
