Remix it, make your planet, and if someone has already remixed it, either remix theirs or grow the remix tree. Also, make the 0 into a 1 and 2, etc. so I know which one it is. Also, do not make the planet/object over 15 cm when starting. And MAKE SURE to not delete the original costumes and name your costume the name of your planet. Also make sure you increase the sizes of the old planets!
also, make sure you duplicate the Your Planet costume before customizing. And make the size range (the text below the planet) of the New Planet you duplicated to triple your size (ex. if your object is 10 cm big say (10 - 30 cm).)
