Disney's The Little Mermaid

The game takes place from a side view and Ariel (Swimming most of the time, but hopping around on the land occasionally) can shoot bubbles to trap her foes and can then throw them at each other. She can also dig through sand to find treasure and pick up sea shells to help her break chests open.

The treasure she finds in the sand is usually just bonus points, but the treasure you find in chests will increase your bubble's power and range.
