Stage 4 (3)

Dive in, swim to the bottom, and hit the switch for underwater terraforming.

Enter the door, break through the bomb block, and carefully navigate the passage until it turns downward.

Go up through the bomb blocks and enter the next door.

Hit the switch, then pull the lever once the bridge closes.

Jump over the switch, grab the key, use it to get the first Energy Sphere, and exit.

Continue down the path to the door at the bottom and enter it.

Keep hitting switches to open paths, grabbing Water along the way if desired.

Enter the door leading to a lollipop, grab it, then swim around the rock formation.

Enter the door concealed by seaweed and blast your way to the second Energy Sphere, then exit.

Continue on, jumping out of the water for meat and stars if desired.

Proceed to the door at the end and enter it.

Proceed along the path, avoiding the large, spiky shell, and grab the Spear ability.

Hit the pink switch, then hit the blue one and outswim the giant shell.

Keep going until you reach the next pink switch, repeat the process, ducking into the alcove to let the shell pass over you. This clears the path to the third Energy Sphere.

Proceed upward to the door and enter it.

Go down the left side, continue down to a rotating sphere with stars and a skull on it.

Run, clinging to walls when you fall from platforms, then throw the sphere at the blocks along the way for a 1-up. Try to stay out of the way of the explosion. The bomb will not explode until flashing and stops ticking when put down until picked up again.

Keep going until you find another bomb, repeat the process, hitting switches to extend bridges as you cannot fly while carrying it.

Cling to the insides to slip through cracks and throw the bomb at the gold blocks at the end to reveal the fourth Energy Sphere.

If a Waddle Dee is a problem, put your bomb down, deal with it, then retrieve your bomb.

Go back to the platform before the gold blocks, slide down the ladder underneath it, and through the door at the bottom.

Enter Eel City. Watch the eels closely and time your movements to get by them.

When you see a place to pop out of the water, do so, and grab the Spear ability if you don't have it.

Continue through the bomb blocks to the top of the new chamber.

Use your spear to hit the bomb block above the upward-facing eel to get the last Energy Sphere.

Continue to the right, through the bomb blocks, and take the exit.
