Help ID filter feeder

Hello guys
Got a new creature on my live rock that seems to be a filter feeder... not sure where it came from or if it's bad... any help is appreciated!

Thanks

Looks like a sponge, harmless filter feeder, and no cause for concern

As above ...

Pineapple sponges are pretty common in newer systems, but tend to fade away with time.
