Little Mermaid, The - Ariel's Undersea Adventure — About this game
Ariel's Undersea Adventure begins with strange currents disturbing Rainbow Reef. Help reopen the Sea Slide, then follow mission stars and Sebastian's advice to aid friends and investigate the weather. Swim with the Control Pad, tap collectibles and use the inventory for useful objects. Treasure hunting adds digging, cleaning and microphone tasks: blow sand away or sing the displayed notes to open a chest. In dangerous waters, choose hiding spots rather than swimming into a threat. Begin with the first reef task and learn the Adventure Screen before searching every corner.
