Why child laughing while swimming underwater in Hydrophobia: Prophecy

[Kaesini]

Hey recently I have get the game Hydrophobia: Prophecy, I like to play this game and I have seen that inside the water polo the character of this game have started laughing like the children’s or some of the child so I don’t know why such thing happens in this game and what are the need for that things is this represent any secret in this game or does it implies something or it I a clue for this game to use, so I am very confused about this laughing of the character at the swimming underwater.

I have seen that the character at the non-titular aquaphobia supposedly has without explanation manifests itself exclusively as the sound of children laughing, and this is due to the oxygen that means that when your oxygen drops to three quarters of its maximum which is always there to make the feet of the character wet. And because of the touching for the feet the character laugh like the child.
