Coloring tips

Use bright red or orange for the lava at the top of the volcano and a dark gray or brown for the mountain itself.
This simple illustration is perfect for toddlers and preschoolers aged 2–4 who are learning to stay within thick lines.
Try using a blue crayon for the background water first, then color the small bubbles and fish with markers to make them pop.
