How to unlock the Junior Hero achievement in Kingdom Hearts Final Mix - Definitive Guide
When you enter Olympus Coliseum, Phil will challenge you to move the stone in the lobby of the Coliseum, however Sora and friends lack the experience to do so. You will notice that in front of the stone is a yellow Trinity Mark which is what you need to move the stone and reveal the keyhole to that world. Unfortunately you will not be able to unlock the yellow Trinity Mark until much later in the game when the Hercules Cup is available. For more information on what lies in store at the Hercules Cup, please refer to Hero of the Coliseum.
Cerberus:
Wait for the Cerberus to stand in place to bite in front of him and wait for the small pause inbetween bites to attack. If you want you can jump on the stands and wait for the Cerberus to put its head down when it spews dark magic on the ground and jump on its back so you can constantly attack it from behind.
Cerberus
Upon your first arrival, talk to Phil in the Lobby and he will ask you to move the stone, after an unsuccessful attempt, talk to him again, then go outside, there Hades will give you a pass to the tournament, return to Phil, give the pass and start participating in the tournament, after winning in the tournament you will have a fight with the boss, having won, we leave this world until we close the well in the world of Neverland, after which we return and win the Hercules Cup as a reward we receive the Yellow Trinity Mark and move the stone that Phil asked to move in the first conversation.
