I had tried to make an entire remix chain where people added buttons to a project where you beat up Spiffy with a selection of user added buttons. After most of it got taken down, I decided to beat up Spiffy again, but with more realistic physics! There are only 5 buttons, and your job is to add more to this! How to add stuff: 1: See inside and make a remix 2: Add more content and buttons to it 3: Change the number of remixes and remove the remix text. 4: Share! Please do not report. I have read the scratch TOS and put effort into these projects (most at least).
C2A, especially for the Beat up Spiffy Extreme and others by @BradBartley31506 and a Beat-up Scratch Cat remix chain.
