W.I.T.C.H.

There was a cartoon show called W.I.T.C.H. that I used to watch on Jetix when I was a kid. In fact; it's originally a comic series which has a good amount of underwater content! it's really unfortunate that the tv adaptation did not continue after the season 2; there could have been more animated uw content. Anyways I've been able to browse the whole stuff so I'll share the excerpts in particular order down below (open the pictures in new tab for bigger size):
