If you are bored with your pet's current appearance, then try evolving it once more.

For re-evolution you will need 1 The Rock of Evolution just like the first time. I know you saw it in the Cash Shop before, so you know how to get it right?

The cost is the same as well, 10,000 mesos. Can't you just see how much better your evolving pet will look?

Your heart's not ready yet? That's disappointing...
