Lets play a game... what is this!!?

So, its white. Its not very fast growing. Its kinda slimy and soft to touch (i had too, I couldn't help it). My bristle stars and peppermint shrimp don't seem interested in it.
Also, its a fairly new tank. Only a few weeks old. I've been searching like crazy but it doesn't seem like anything others are mentioning and it is white, not brown or light brown or anything.

Sponge for sure. I can't tell if it's a pineapple. Either way it's a good guy!

I haven't really looked much into sponges yet. I hope its a pineapple sponge though just so I can show my pineapple hating friend how much I really do love pineapple.
Ok, Google search time. Hopefully this one matches up!!
