Splice CLIFFSIDE and MARS ROCK to make ROCK PLATFORM. Category: platforms. This thing grows like weed... NOT that weed you silly. ROCK PLATFORM gives experience points when broken. How many times you need to hit it? Head to the wiki for more info: <a href="https://growtopia.fandom.com/wiki/Rock_Platform">rock platform</a> You get at least 1 seed back (maybe more!) from splicing ROCK PLATFORM. Profiting with this might be questionable. Massproducing ROCK PLATFORM can be tricky. You will find out after you have harvested a few.
