I'm OBSESSED with Disney Channel's Fish Hooks. It's about 3 teenage fish friends living in asorted aquariums in a pet shop. It combines photo collage animations (think if Eric Carle and the Monty Python animations had a baby) with traditional animated characters. Children's book illustrator Noah Z. Jones is the creator.
But what I'm really obsessed with are the supporting characters such as Clamantha the yearbook editor clam, Shellsea-the main character Bea's beastie, Mr. Baldwin-the pregnant seahorse teacher, and Jocktopus-the football playing jock octopus.
The voice of Clamantha (who by far is my favorite) is by Alex Hirsch who made Off the Wall, a short about a doodle on a wall named Wallby. It made the rounds for awhile on art/animation blogs because he was a student at CalArts at the time, and because it's hilarious.
It's called obsession for a reason. You do your research.
