Throughout the course of the game, Ecco will gather several gifts which will be used to defeat enemies, pass thresholds and gain more powers. In addition, Ecco will learn several songs from sympathetic sea creatures. These will help you communicate to the other animals in the ocean. Many times, you will use them to assist you in your quest. Some are just food that heal wounds and infection.
Some fish glow like torches in darkness, and red fish of poison repel enemy attentions.
Sharks will be stunned with the sound of your sonar. For the briefest of instants they will not attack, and those so confused may head-on be battled. Turtles now trust you and follow your leading. They follow the song one by one in a line. Frightened by charges they shyly sink downward, but this song renews their trust in you at once.
