Hydrocity Zone is the second zone in Sonic the Hedgehog 3 (or Sonic 3 & Knuckles). This is the most water-filled level in the game, and several parts of the level takes place underwater. This is also the only level in the game to feature the air bubbles (except the bubbles inside the balloons in Carnival Night Zone), which prevents the character from drowning. However, if you find a water shield you don´t need the air bubbles.

[edit] Boss

The sub-boss this time around is Big Shaker, a spherical contraption with four rockets. This device spins back and forth through the U-shaped pit in which you are standing, before settling on a pole set in the middle of the arena. It's only safe to attack the device while it is in the middle, at which time it will have begun to turn the pole, which in turn stirs the water, and your character. However, you can Spin Dash up the side and attack while it is off-screen without getting hurt. Though the boss itself is relatively simple to beat, remember that Sonic & Co. can still drown while underwater.

[edit] Trivia

  • In the first act, statues resembling Sonic can be seen at the top of the background.

[edit] Glitches

  • In Sonic the Hedgehog 3 (alone), during the mini boss, if Sonic (and/or Tails) stands underwater until the "Drowning" music kicks in, jumping out will play the Sonic & Knuckles miniboss music. This trick also works for the battle against Eggman. Sonic 3 & Knuckles has this glitch as well. Another thing worth noting about the mini boss is that in Sonic 3 (alone), the "Major Boss" music plays instead of the "Minor Boss" music. The Sound Test for Sonic 3 contains most of the music from Sonic & Knuckles, including its "Minor Boss" music; Sonic & Knuckles' Sound Test blocks out all Sonic 3 music.
  • In Sonic 3 (alone), during the fight with Eggman, if Sonic is Super Sonic and gets caught in the whirlpool that Eggman's machine creates, he will transform back into regular Sonic, but remains golden; his quills will drop down like normal. He also stops losing rings. This was fixed in Sonic & Knuckles.
  • In Sonic 3 (alone), when Knuckles destroys the bridge, hold down right on the Dpad. If you do correctly, Sonic will be able to bypass the battle with Eggman and head straight to the capsule (you have a higher chance of doing this if you're Super Sonic). Opening the capsule will clear the zone, but the game continues with Sonic doing his ending pose, and he won't be able to continue to Marble Garden unless you reset the game. Bypassing the capsule will let you, with the help of Tails, travel to the point where Hydrocity Act 2 "loops back" (repeats the level layout). It should be noted that unless you destroy the capsule, you can still go back and fight Eggman as normal, but if you open the capsule, and THEN defeat Eggman, the capsule won't be there! You can also perform this glitch by simply running to the capsule, and then running back to defeat Eggman. All of these glitches were also fixed in Sonic & Knuckles.
