Part 4

After learning to hop through portals, proceed right to a puzzle room. Jump into the dead portal, then the living portal, and use Rooster Uppercut to land on the upper-right floor. Use the dead portal to get the Stamina Chunk, then the living portal to exit.

Climb the next room, hitting the dead portal to activate platforms. Note the yellow block on the left (*MARK IT* for later). In the room above, you'll find a shop and two doors (dead world and living world). The game suggests the right (dead) door first.

Right Door Path: Head right down the corridor. Bust the red block to wake the Alebrije, then climb the shaft. At the top, go left into an arena with 1 Esqueleto Tropas (living) and 1 Esqueleto Tropas (dead). You cannot damage enemies in the opposite world, but they can damage you. Use portals to switch worlds and defeat them.

The next room is an arena with 3 barrels, 1 Armadillo Rodando, 2 Armadillo Rodandos, and 1 Armadillo Rodando (living) and 1 Armadillo Rodando (dead). The game warns you cannot dodge fire attacks; jump over them or punch them to halt them.

After clearing the arena, drop down, roll through spikes, and fall into the Alebrije's cage. Climb up and jump into the ceiling. To the right, find a Choozo Statue. Break it to get the Goat Jump, allowing you to stick to walls and jump off them.

Use the Goat Jump to leave the area by wall jumping up the shaft to the left. A sombrero chicken will explain that holding the grab button lets you hang on walls without sliding.

Navigate the jumping puzzle: Jump left, walljump to the dead portal, walljump to the far living portal, walljump up to the dead portal, and use Rooster Uppercut if needed to reach the left platform.

Go down the left shaft to return to the starting area. You can now enter the left door.

Left Door Path: Climb the room, jumping through the dead portal to activate platforms. Kill the Tropas and Rápido enemies. Go up the platforms on the right, avoiding the living portals. At the shop at the top, go right first into an arena with 2 Armadillo Saltos.

Take the Stamina Chunk on the right. Return to the left of the shop into an arena with 8 Esqueleto Lanzadors. You must run back and forth, activating/deactivating platforms until they fall into the lava.

Head left to a treasure room. Four chests contain Esqueleto Tropas, and two contain money. Break all chests for completion.

Exit left into another arena with 1 Esqueleto Gigante (living), 3 Esqueleto Tropas (living), and 3 Esqueleto Tropas (dead).

After defeating enemies, drop down and break the Choozo Statue to obtain the Olmec's Headbutt. Use it to break yellow blocks.

Use the shop and break the next two yellow blocks to exit. These teach you that the headbutt can be used in the air, even after a Rooster Uppercut.

The final room before looping back requires you to roll through spikes off a platform and quickly interrupt the roll with a Rooster Uppercut as you touch a portal to land on a new platform.

Re-Merge: Go back to the *MARK IT* location (yellow block below the current room) and break it for a $500 chest.

Head up the shaft where the arrow points. At the top, turn right. Navigate the walljump puzzle, using Rooster Uppercut to get under a pointy wall and high enough on the right wall to jump left. Slide down and jump through gaps to get the Heart Chunk.
