For this you must beat the 2 levels and also the Final Boss mini level which are: Dungeons And Chimps, Storm The Palace, and Zartog's Demise. After clearing that zone the achievement will unlock.

The first level is probably the easiest to get this achievement on since its short, the enemies are easily defeated, and there is not a lot of tricky sections to navigate. Just make sure not to die by falling off or from the enemies.

The earliest you can get this achievement is on the 3rd level since you can not do it on the first level and you don't get control back of Ham until level 3. So just take your time, plan out your route and make sure not to fall off anything through the whole level if you want this achievement.

To beat a level in under the required time will mean you must avoid fighting all enemies unless they open a door for you and re-spawning far from where you died. You will get the layouts of the levels fairly quickly since they are all quite short and easy to navigate aside from the last few levels. So make sure to collect everything you need to collect before attempting the par times because every second will count.

Final Boss - Directly in front of you, just on the ground between the silver statues.

Collecting Globhoppers, and the Dole Bananas, and also beating a level in under par time will unlock bonus content such as concept art, videos, and costumes for the characters. So working on the collection achievements will net this when you collect everything there is to collect in the game.

After you defeat the final boss a cutscene will play, and then the credits roll. they are only a few minutes long so just sit back and DO NOT touch any buttons on the controller, or you will have to replay the final boss to get the credits again.

Do this on the first mission and kill every single enemy you come across buy hitting them with your X button. Enemies are killed with one or two hits on this level so just make sure to kill all that you come across.

Globhoppers kind of look like gummy bears and are various colors, you must search a little bit for a few of them, such as behind trees and so on, and some are easily missed, but they are bright colors and they are not hard to spot once you know what to look for. You can use the level select option to replay levels which you will have to do anyway for time trial missions and learning the levels. So if you miss any along the way the first time through the level you will have ample opportunity to be able to find any you missed.
