Underwater volcano with octopus and fish – free coloring page to print · Doodleur

A cartoon underwater volcano erupting with a cloud of bubbles. A smiling octopus sits on the sandy floor next to a starfish, while several small fish swim through tall stalks of seaweed. The drawing uses thick, bold lines and simple shapes.

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.
