Name: Rila Westen
Nickname: Mother Goose
House: Life
Age: 46
Species: Still ostrich
Bio: Rila Westen is the diligent mother of over 136 children, a record that is not only renowned, but ever growing as well. But what makes her record even more famous is that none of her children have kicked the bucket. That's because she's not only a good mother, but tough as nails, too. You will often see foolish thugs in the hospital after Egg Legs has her wings and talons over them.
It's also known that ostrich eggs are very big. One ostrich egg can birth three children. And Egg Legs always has an egg around. She often uses her eggs in many different ways. When she loses an egg, she quickly hatches a new one. She became the head of the Life House in the Elemental force, where she continues to nurse and mother her children. Who better to lead the "Life" house than an experienced mom?
Abilities:
A: Angry Birds: What can Egg Legs do with her eggs in Angry Birds mode? Her eggs are usually infertile, so they make perfect weapons which she can use to smash and toss at her opponents. The ones that ARE fertile contain children that fight along side her, and exit the battle when they've had enough. Yay overly kid-friendly content! Finally, she can crack open infertile eggs to reveal a hot, yolky goo which can damage targets and slow them down when they step on it.
B: Mighty Matron: Mighty Matron showcases Egg Legs compassion for her children. Always protecting her giant egg, she can jump over her egg and kick a target in front of her egg. She cannot deal as much damage as her egg slam, but it has high priorities. She can also summon kin in this form, and regardless of form, the children attack on their own. When Egg Legs gets worried, she can rush in and smack opponents her children are fighting, and even lob her giant egg at them.

Edit: Changed her name to Mother Goose. It sounds better. Also changed her first attack in Mighty Matron cause it didn't fit her.
