Yup.

Bringer of comfort; smaller when near;
Gone with the sunrise; for now, though, I'm here.

The albatross?

The cat at the tombs in hhb?

Good guess, Jaygee, but Trufflehunter's answer is correct.

I really like this game!

I used to talk but now I'm dumb.
I called but didn't think he'd come.
I walked inside with tail held high,
But flew back out with a high-pitched cry.

Gingerrrrr?

Correct!

Uh-oh, that mean's it's my turn agaiiiiin. 😕

I am an object, found in a room,
Later am another creature, but turn back very soon,
I'm really quite crudely made,
And a bit big for human use,
But whatever, talk to the Nurse.
What am I?

The toy elephant? (was it an elephant? Gah, I'm not sure.)

Rocking horse, wasn't it? *inserts her guess*

Yup! Your turn, Tenny! 😀

Rash, Angry, Bold, Awful, Daring, Abominable, Sneaky, Hopeless.
Who am I?

Alex looked at the riddle and said, "...Gollum?" 😆

My guess is Rabadash? It's probably not him, but oh well. 😛

*snickers* good job, Hobbit!!
It /is/ Rabadash. 😉 I'm not good at riddles. Your turn!
