Bonus levels:
Unlock the following levels by collecting all three pieces of the corresponding maps:
BuiBui Fort 3 – Smudged map
JaoJab 3 – Coarse map
Kelpaton 2 – Soggy map
Perculoka 2 – Bumpy map
MuiMui Crane mini-game:
Expand your MuiMui House, and build a MuiMui Crane object. To grab objects with it, press Left or Right to move around as the crane is descending. Keep playing, and a BuiBui will eventually appear with a larger claw. This allows some hard to get items easier to obtain.
Video clips:
To unlock a short video somewhere on the map and under “One Day…” in the “Memories” menu at the MuiMui House, beat a level with 20 LocoRocos.
Alternate main menu:
To unlock an alternate main menu, remain idle at the main menu until the LocoRocos begin playing around and go to a playground design. Wait for them to go through Dokkola and cannon, wheels, Chuppa, Nyokki, the sound wave, air current, and Mui Mui crevice. Tap R when they reach the rotating bowl. The Mui Mui will pull a lever, and the bowl will tip to the right. The LocoRocos will now go through an alternate playground.
Fight against Galanmar:
To unlock the final Boss, get rid of the Moja Bunyo (black clouds) from all levels, including the bonus levels.. To see how many of them are remaining, press Triangle at the world map to zoom out and check the counter.
Easier “BuiBui Fort 3”:
Keep jumping to prevent your LocoRoco from straying or jumping from an edge. Reach the Chuppa, then fire at it when it tilts backwards almost all the way.
Defeating Majoline:
To defeat the third Moja Boss, jump and hit her eyes. To do this, wait for her lip to raise up so you can get close enough to hit them.
Defeating Mutated Bonmucho:
To defeat the second Moja Boss, aim at the grey nostril hairs. Once you have one held, press L R to pull it out. Do this three times to defeat him.
Defeating the final Boss:
To defeat the final boss, Tap Circle to rapid fire when she does a lethal charge at the very end. Keep doing this during the final charge.
