This is Gandalf praying and wishing:
1. He wants a bone.
2. He wants a new bed.
3. He wants Milo to stop harassing him.
4. He wants to meet another female aside from his mother and sister.
5. He really wants to get a bone. And wants it bigger than Milo’s.
Oh, well. Sometimes wishes do come true, Gandalf, if you concentrate enough.
