如图如题,其它所有成就都完成了,就剩下out of this world,quick finish2,taste for destruction这三个成就了,请问该如何完成呢?

Name:Out of this World
Game Center Points:10
Description:"Find the Planetarium!"
Tips:You must find the hidden solar system-inspired stage (and that's it - you don't even need to beat it).To find it,hit "Play" on the main menu and then tap the "Achievements" button.Drag the screen down with one finger (so the framed achievements go towards the bottom of the screen) until you see a doodle of the planet Saturn.Tap it with your other finger to play.
Name:Quick Finish 2
Game Center Points:10
Description:"You finished Level C1-5 with at least 500 Time Bonus points!"
Tips:Cheekily enough,this achievement requires the premium download pack Cranky's Story.If you've got the DLC,head to "Cranky's First Course" and choose level 5.You need to quickly drop the purple water closer to the algae,then direct the water into your pool to increase your purple stash.Then,drop the whole lot through the algae and into Cranky's pipe.Do it fast enough and you'll nab the achievement.
Name:Taste for Destruction
Game Center Points:None
Description:You need to own the premium content pack,Cranky's Story,to find this secret level and unlock this achievement.If you have the pack,open the Challenges menu,pull the screen down with one finger and tap the skull that appears with your other finger.You only need to open,not finish,the level to get the achievement.
