I think mushrooms will be able to be used in other worlds but only if you use the coffee bean. I doubt coffee bean would be premium because that would be really stupid for mushrooms to be only in one world. Popcap would never do that. The premium would be something more along the lines of something awesome and really useful (ahem: Doom Shroom!). Coffee beans waking spring beans though? Maybe. And waking Coconut Cannons, VERY unlikely. But it just makes sense for coffee bean to return. And if it does  im guessing it will be the last plant you will get at the end of the world
