I got way more guesses than I expected, so I'm updating this sooner. I guess these poems were actually hard! The guess success rate was pretty low, sorry guys.

So #1 was Nightcloud, Crowfeather's second mate! Nobody got that one.

#2 was Spiderleg! Starrysong Likes Spring and Splash of Thunder in Mist got that right! Points for them!

#3 was Tinycloud, from SkyClan. You probably wouldn't have known her unless you read one of the super editions, can't remember the title. Sorry about that. :P Nobody got that either.

Here's the current score:

Splash of Thunder in Mist: 1 point

Starrysong Likes Spring: 1 point

Make your guesses for this round to earn some more points! I'll try to make it a bit easier this time and use more well-known cats.

#1:

My disappointment was like strange water

A gray pool instead of blue

After one night, never whole again

Killed by a crush of rocks

And that was the end

#2:

Started in one place

Continued in another

Staying in the first place

None other than my brother

In the new place I gave life

To tiger, dawn and flame

One of them is dead now

And StarClan is to blame

#3:

Born with silver feathers

Always by my side

Through loneliness and hatred

Together we'd abide

To mountains we would journey

And heroes we would be

But rocks that saved the many

They set my sister free.

Good luck guessing! Leave feedback if you think they're still too hard. I tried not to make them too easy.
