WRONG WAY (5g): Run to the left to find a magic egg. Step on it to receive an achievement.

Drag the crate out of the pond. Position it under the hanging rope. Swing up, climb the branches, and push over the broken portion. Use this to cross the pond.

- ALTITUDE IS ATTITUDE (5g): From the top branch, jump left onto a partially hidden rope. Climb halfway up and swing left to reach an achievement.

Continue on until your reach the giant spider. Beware of his initial attack, then get him to strike at you twice more. This will knock down the bear trap from the branch you just passed under. Use this trap to catch the legs of the spider as it stabs at you.
Continue on until you are inevitably wrapped up in the spider’s webs. Wiggle around to drop from the ceiling and hop along until you reach a loose boulder.

Push this boulder and quickly move back to avoid the falling tree. Keep going until you jump down onto a larger boulder. Ride this to safety. When you reach the hanging rope, be careful not to swing forward at first to avoid a falling bear trap.

Leap from stump to stump and onto the thin branch. Move back quickly to avoid the falling log. At the segment pictured above, jump onto the middle log then straight up to avoid the swinging boulder trap.
You’ll encounter some mechanical spider legs - be careful and run underneath. Jump across the pit, but run and jump back over once the flaming tire comes rolling toward you. Now continue on. You can simply jump to avoid the rolling rock, but hurry or you’ll face another flaming tire.

Once you pass the hanging corpse, get ready for some maneuvering. Inch forward until the first bear trap swings down, then move a step or two forwards again to avoid the second. Climb the rope to your left to proceed.
You’ll reach a log - push it into the water quickly and jump on. Leap as soon as possible from the log and continue on. When you reach the see-saw, stand on the right side until the spider raises you up. Jump quickly to the ledge and keep going.
Eventually the spider will fall into a pit behind you. Proceed right to trip a boulder trap. Run back to the left, drop down, and let it roll overhead and crush the spider
When you reach the spiked pit, the spider will return once more (less threatening this time). Let it stab at you. The spider is now dead dead. Pull his leg off and push the body into the spike pit to proceed.

Climb the ladder and move left. Jump onto the hanging crate with the raven on it. Hopping will make it fall. Use this crate to reach the ledge below.
After using the floating bodies to hop across the water, drag one of them with you and push it into the trap ahead.

When you reach the trap pictured above, make sure to jump onto the raised segment to avoid death. The next trap operates the opposite way - avoid the raised segment. Once you jump across the spike pit, three enemies with blow guns will chase you. Run back to the left making sure to avoid the traps and the not so wise enemies will be crushed.

At the bottom of the ladder, there is a mine cart to the left. Pull it to the right as far as possible, then grab the rope above the saws. Climb the rope as it drops to avoid death, then hurry below and jump from the mine cart to catch it before it retracts above the saws. Swing from this rope to the next, and once the two weights are even with each other, jump to the right and run underneath.
You’ll reach a glowing maggot hanging from a tree. You’ll learn you can’t avoid these. You cannot control the direction you run in with this maggot on your head, but it hates direct light. Make sure to jump at the bottom of the steep hill to avoid the water and you’ll find a crate. Jump over the crate.
When the light forces you to change direction, push the crate along and then jump on it when under the hanging munchers to remove the head maggot.

You’ll encounter a timid frog trying to get the hanging glowy yum-yums. Hop up and down on top of the ledge containing these treats to coax the frog out. Quickly get between it and its hiding spot on the right. This will force it left instead and into the spinning wheel.
Pull the lever and hold it until the rain turns on. Continue until you reach a hanging chain. Fall into the pit beyond this and pull the log into the center of the pit. Climb out via the ladder on the left. Grab the chain to connect the pipes and fill the gap with water, allowing you to cross.

At the bottom of the slope, push the crate along until it is underneath the trap door. Pull the lever to the right of the ladder, then quickly climb up and pull the trap door open. Jump onto the rising crate. When possible, jump from the crate to the ladder. At this level, pull the crate out from under the ledge and hop on. Once the water rises you can reach the ledge above. At the top of the slope, take a flying leap, grabbing the ledge below as you fall. Pull open the trap door. The water will cause a ball to rise. Once it does, close the trap door so that you can push this ball to the right. Line it up with the crate above, then hurry up the ladder and stand on the crate. Be quick about all this as the timing is very tight.
When you reach the ladder, run past it and pull the lever. After the water rises, pull this lever again. Climb the ladder and jump across the water. Pull this second lever and you will be able to cross.

Another head maggot... Before it latches onto you pull the crate out from under it and all the way to the left. Let the maggot hop on, then use the crate to reach the ledge above and enter the light. This will turn you around so that you can proceed across the ladders.
You cannot change direction with the head maggot attached but you can slow down. Carefully jump across the breaking pipes until you reach a second patch of light. This will turn you around.
The water is rising now so hurry all the way back to the first patch of light in order to face the correct direction. Jump on the right ladder and wait for the water to raise a section of pipe. Use this pipe to make the jump to solid ground. Jump so the hanging munchers eat the maggot off your head.
