Need help identifying this orange on my new rock and also what type of plant is this

Hi guys I need help identifying what this orange is on my new rock and also the purple plant on it. I was told it was a sponge but I don't see tubing any where for a sponge does a sponge have to have tubing and it's hard to the touch not sure if a sponge would be pretty solid on a rock? Any help is appreciated helping identify both of these thanks!sorry for the glare on one of the images tried to get best pictures I could
