Ecco the Dolphin

Ecco the Dolphin is an adventure game released for the Sega Game Gear, Sega Master System, and Sega Genesis involving the adventures of a young dolphin named Ecco the Dolphin. His characteristic feature is the stars on his head arranged in a unique pattern.

Story
One day, Ecco was challenged by a pod member to see how high he could jump. Upon accomplishing this feat, a water spout occurred and blew his entire pod away. Ecco then set off to search for his pod.

Gameplay
Besides swimming and jumping, Ecco can eat by dashing at food in the form of fish. Food heals him after he is injured by enemies such as jellies. Being that he is a mammal, Ecco must occasionally surface to breathe. Not doing so will hurt him over time. He also can communicate through echolocation, from which he gets his name. His echolocation is also used to bring up a map.

Japanese version differences
There is an extra level named "The Stomach" which takes place after the final boss. It uses artwork not found elsewhere in the game, and the sonar does not display correctly. This level only appears in the Japanese Mega Drive version. It is speculated that this was an unfinished concept level that was accidentally left in the game. All data associated with this level was removed in all other versions.

After beating this stage, the ending plays as normal.
