Hi Sara!
To make a flower you'll need a "planter" and something to make the flower sprout (right now that means... water). We're presently working on revamping a lot of the combinations and adding more paths to lots of items. If you're working on the "a beautiful sight, but watch out for my bite" riddle, the 3 star answers aren't actually possible to reach because of a bug in the code. We should have an update out this evening to fix a lot of issues, so look forward to it :)
Also, than you for the rest of your comments! I'm really glad you're enjoying our game so far, and we'll definitely use your feedback to help us improve the game.
