Click the green flag. Click the smaller flag inside the project to start creating your line. Drag your mouse or your finger on the cat. Click it to change the mascot. Click the stop button on the cat’s bottom right corner to stop. Click the restart button to restart the line.
I got this idea from @natalie’s project, Colourful Trails. The link is here: https://scratch.mit.edu/projects/10001052 Hope you can make your very own colourful lines and remix this! -Gica a.k.a. @MagicBFFSANTICS
