Co-op Level 4

Co-op Level 4 is the fourth Co-op level, and one of eight multiplayer levels.

It takes place in Lavaworld.

Beginning
One Marbleball powers a floor fan and the other goes on it, then pushes a wooden crate down so the first Marbleball can power the floor fan to fly up to the first checkpoint.

Checkpoint #1
One Marbleball turns into the Metalball and pushes a stone ball onto the left switch to power a floor fan, then goes on the right switch to power another floor fan. The other Marbleball goes onto the floor fans and pushes down a wooden crate to power the lower floor fan so the Metalball can change into the Marbleball and go up to the higher platform to the second checkpoint.

Checkpoint #2
One Marbleball turns into the Airball, disables a fan and goes in front of a lever, while the other turns into the Powerball and turns on a switch for the lever to push the Airball. The Powerball jumps to the next platform and the same thing is repeated two more times. The Powerball turns into the Airball and both Airballs use five pumps to fly to the next platform and the third checkpoint.

Checkpoint #3
The Airballs turn into Marbleballs and turn on timed switches to open two gates, then they go across two hanging platforms and through the gates to the fourth checkpoints. If one of the gates close on a Marbleball, there are rails on the left.

Checkpoint #4
One Marbleball turns into the Metalball and pushes hanging metal boxes to the side, while the other turns into the Airball and goes past the boxes. The Airball flies to a switch to turn on a magnet, while the Metalball turns into the Powerball and sticks to it. The balls go to the fifth checkpoint.

Checkpoint #5
The Powerball turns into the Airball and both Airballs fly to the next platform. One Airball turns off a fan so the other can go through, then the second Airball gets pushed by a fan to another platform to turn off a fan so the first Airball can past. The first Airball turns into the Metalball and pushes a wooden crate onto a switch to turn off a fan. The second Airball turns off the fan to let the first Airball pass. The first Airball turns into the Powerball and turns off the fans so the Airball can change into the Powerball and finish the level.
