Click the green flag to switch costume and create a new spiral. When you're done playing around, check out the original project and try making your own remix :)
Thanks to @Daffodil_alias_Daffo for the original project Sprite Spirals: https://scratch.mit.edu/projects/796852535 In this re-remix, all costumes use the same watermelon graphic from the Scratch library. The only difference is that I have rotated and/or changed its position.
