This is the hardest achievement in the game. For this, you don't need to get all of the smiley murphy faces (though it is recommended), but you need 100% or five stars at the end of every chapter. To make sure you meet the unknown score requirements, explore every level before grabbing any gems or defeating any enemies and come up with a strategy to make the biggest combo you can get using power-ups (you get 2x points while using one!). While you are making a combo, grab the yellow gems first and keep the best stuff (like green gems) for last - but if you're using a power-up, make sure this doesn't run out before you've grabbed everything! This will allow you to score extra.

See end of guide HERE for a chapter by chapter breakdown of how to get the highest score possible.

Teensies are found in cages suspended by ballons and they look the same throughout the game except for on the level "Land Of The Livid Dead". You will get the majority of the cages as part of the story but some of them are missible. You can tell when you are near to a cage as they cry out for help. Just smash the cage with your fist attack to break the teensie free. Every six cages you collect increases the size of your health bar so finding all the cages has an added bonus.

Matuvus are best described to look like blue lizards. They are usually found clinging to walls or on ceilings. To get the bonus score of a matuvu you must enter look mode by holding  and look at the matuvu until a red circle surrounds it and you get your +250 score. You can tell located a matuvu by the whistling noise they make. There is a total of 40 Matuvus to collect.

Tribelles resemble red flowers and glow slightly. They make a distict shimmering noise which is easy to recognise. To get the bonus of a tribelle you have to walk up to them slowly, if you approach they will disappear and you will have to restart the level to try again. Only push the  gently in the right direction to walk towards them until you get your +250 points and they fly away. There is a total of 13 tribelles to collect.

Green jewels give the highest score of all the jewels - 1500 poins. Some green jewels are given to you by teensies in hidden cages, others are well hidden. These are best collected while in combo, with a superpower or both in order to gain maximum score. These jewels are very helpful for "Perfection needs no arms" and can make all the difference. There is a total of 41 to collect.
