This anime is called Tokimeki Tonight. It's a very unusual anime...for one it was made before the manga, which usually is never the case. The stoyline about a family where the mom is a werewolf (she's really pretty, and her werewolf form is actually pretty cool
) and the dad is a vampire who can go out in the sun if he has sunglasses on...unusual, but it's funny the situations he gets into XD.
The main character is a girl who has an unnatural ability to transform into anything she bites into with her vampire teeth. The only way she can transform out of what she transforms into...is by sneezing. That makes for some interesting scenarios XD.
She sneezes as a bird, two different cute girl puppies, a boy cat, a big bear, a shark, and a number of different things. People and objects. The girl herself has a cute design
If anyone is interested I could find exactly when she sneezes in each episode as an animal. (I'm hoping that her mom as a werewolf would sneeze
