I know we have the Zenirix already, but we need a wolf.  I thought of a a creature that is like a wolf and it's called Darlu (Dar-loo).

Baby- It has white tiny wings and is light grey.  It has tiny paws and one eye is closed and the other is open and it is curled up about to sleep.  It has blue eyes too.  It is beginning to grow claws and has a bushy tail.  It also has a halo.

Teen- It is sitting looking up curiously and it's wings are now a bit bigger.  It's claws have grown larger and it's tail is longer too.  It still has a halo and it is more furry.

Adult- It is flying looking at you.  It's fur is still furry and it's tail is the same.  It's black claws are now very sharp and pointy.  It's wings are large too.  It's halo is still there.

 I hope you like my idea!
