The Triforce one is my favorite, but I also like the music note, the citrus one, and the AC leaf. I have a stump garden where I tried to get one of each and now I kind of want to add a normal stump because I missed that one.
I love the Triforce, but I'm being bias cause my town is loz theme so I think it's a cute detail!
I also love when Nintendo references other titles in their games. Of course the heart is also adorable and I have to say my least favorite is the ginko...
