Create a vertical, cartoon-style illustration of a treasure map set on the ocean

Create a vertical, cartoon-style illustration of a treasure map set on the ocean. The map should feature three distinct islands, each progressively larger as you move downwards on the map.

The final island at the bottom should be the largest, featuring an X marking the spot where a treasure is hidden. Include some playful elements
