MAXINE and NATALIE (the cows)

[punkNpuppets]

i was looking at the post Muppetdude did and i noticed he said that he THOUGHT the brown muppet cow was named Maxine. does anyone know if her name is REALLY Maxine and what sketches she's been in alone? what about Natalie, when has she been called NATALIE? and what sketches has Cathlene been in?
