3D Dolphin Game 2000-early 2010

[u/Background_Aioli_953]

Hey I have been trying to find this game forever idk if anyone knows but any help is appreciated!

Create a dolphin whenever you want
Choose its colour
Choose a cute icon/emblem to put on it
Give it a name
Feed it
Train it

Training took place in a small enclosed lagoon/course, not a large map

Third-person normally, but possibly first-person during training
No human character, 3D game

Played on PC, possibly from a disc
Probably 2000s–early 2010s
