Yellow Submarine Adventure
A small yellow submarine with a round porthole carries a waving captain, while curious fish look in from the outside. Color the submarine bright yellow and the porthole in shades of blue to show the ocean view, and make the fish colorful and friendly-looking. Free to print (A4) for ages 6-9.
