Part 14

Grab the first turtle and carry it to the slide-canyon dropoff point. Both brothers can carry turtles, making it faster.

Drop the first turtle down the slide into the water; it will join its mother.

Move the second baby turtle, located next to the slide, a few feet to let it roll down.

Return to the hilltop with the broken rope ladder for the third turtle. Have Big Brother hoist Little Brother up to the turtle. Push the turtle to make it slide down to Big Brother.

Carry the last turtle to the slide and send it down.

Find the guide up the cliff after sidling across the ledge. Follow her to a tree.

Head up the slope to the left, past the saw, and jump to the bench to trigger the game's final achievement.

Have both brothers sit on the bench to receive the "Whale Song" achievement.

Return to the saw in the tree and interact with it as both brothers. Saw the tree down by sliding the saw back and forth with both movement sticks.

Bring the saw to the tree next to the women and saw it down.

Cross the chasm using the felled tree as a bridge.

Follow the women across another bridge to the drawbridge of a city.

Push the catapult forward until it slides down to the drawbridge entrance.

As Big Brother, man the catapult lever and fling both women and Little Brother into the city.

As Little Brother, rotate the lever to lower the drawbridge.

As Big Brother, enter the city and go to the women. As Little Brother, squeeze through the gate and follow the upper level.

A cutscene (a non-interactive cinematic the game plays automatically) will reveal an invisible monster terrorizing the area.

Head north through the city, navigating Big Brother on the lower level and Little Brother on the higher level.

Reach a gate on Little Brother's side and a wall on Big Brother's level. Use the wood rafter on the wall to jump to the opposite rafter, then down to the gate with Little Brother. The women will jump across normally.

Wait for the women to open the gate, then run to the frozen statues and interact with them to hide from the invisible monster.

Follow the women up to the road. Wait for her to jump to and turn the crane.

Grab onto the crane and she will rotate you over to her.

Drop down and head to the next set of frozen statues. Hide behind them to evade the invisible monster again.

Wait for the women to leave before following her up stairs, past a well, and into a house. The invisible monster will destroy the house.

Warning: You must outrun the invisible monster by darting across the bridge. The lanes are slightly different for each brother, so be aware of turns to avoid getting hung up. This part may require multiple attempts.

Upon succeeding, you will reach the end of Chapter 6.

Follow the women into a cave-like structure.

Crouch through a small tunnel in the cave.

You will end up in a ball of webs with a giant spider. Swing the web ball back and forth until it falls to the ground.

The spider will try to grab you. It will pin Big Brother to the ground.

Boss Fight: As Little Brother, roll into the spider with speed to knock her over.
