Halloween Cat Bowling Witch

Can you help me name these books?
These two I had when I was a kid in the mid 90s. They are both picture books. The first was a girl with a dining room, the room was tired of being disorganized, so go to your school to request cleaning. There was a world, a fish tank bed dirty, wrinkled, etc.. The second was about a girl dressed as a witch for Halloween with her cat, they found a cache of shopping for witches, apples poisoned, brooms, etc.. Another but rather far-fetched because there are many books about dancers .. I do not remember, but there was a girl who went to ballet class and I think his shoes were magical and helped to better dancing. She butterflies when he had to perform.
idk about the first but the second could be a very brave witch by Alison McGhee http://search.barnesandnoble.com/A-Very-Brave-Witch/Alison-McGhee/e/9780689867309 mail could be the last Magic dancer: Ballet Shoes and Magic Delphi but that's like a series if I remember correctly it could be magical ballet slippers Nick Ellsworth http://search.barnesandnoble.com/Magical-Ballet-Slippers/Nick-Ellsworth / E/9781435111424 /?
