Are there any free stuffs or stuffs that can be trade?

Like the title, are there any free stuffs or stuffs that can be trade? Well, if not, then yeah, just say "No"

I'm wondering why I asked this, well, it's bc I CAN'T EARN BUTTONS ANYMORE, and I only have a red spray paint from Mimi. IDK why I cant earn them anymore, if anyone knows why then plz type their suggestions here, and I'll try to do it?
