Altar Emerald

Altar Emerald is the final level of Sonic Advance 3 and holds the final boss, which is another one of Eggman's machines.

Gemerl also appears before you fight Eggman. He is more difficult than any other Gemerl (excluding Nonaggression).

As the name suggests, you fight at the Master Emerald Altar. Eggman uses these attacks with his machine, Slam Hand, Punching, and Pong.

Slam hand is where he slams and pushes the ground down where you can then jump on the hand to attack him.

Punching is where he pulls his hands back and tries to punch you.

Pong is where his hands bounce back 3 red balls which you can jump on and attack Eggman.

After you defeat him, all the characters come to the Altar to celebrate and Omochao takes a picture, then the credits roll.
