Underwater room Glitch or Improvement?!?!

Today I was waddling around in Club Penguin, I decided to practice my Underwater breathing. I swam into the Underwater room, and I found that the mossy key pin was GONE!!

 

And the yellow fish was GONE!

Does this have to do with the Underwater Expedition? I wonder.... I hope our little fish friend comes back :)
