Create the number twenty ('20') with a bold outline. The design includes the '2' and '0'. Inside the '0', which is a circular shape, place up to 5 small, proportional toy images such as small trains, balls, or stuffed animals. Important: Ensure that the number '20' and all toy images inside the '0' have no internal color whatsoever—only black outlines. There should be no shading, filling, or any color other than the outlines. Inside the '2', add minimal detail or leave it plain. Ensure all elements stay within the circular part of the '0', with no lines or divisions inside.
