The Secret Ammo Box: On level 4, Go to your right and the first gap you see, jump down it. Yes, i know it goes against video game instinct, but commit "suicide". You will find you land on a platform down below. Walk to your right, and there will be another small gap. Jump OVER it, not down it, and continue on. You will find a box with a halo. This is the Secret Ammo Box. Walk into it to get the achievement.
Weebl's Secret Island: Ok, don't freak. There is basically infinite space but the island is really close by. On level 13 go to the right to the edge of the pink. from there go up, into the Out of Bounds Zone. Go up until the stars stop. Keeping within the stars, go right again and you will quickly find a pink square. Click on the Trophy inside the pink Square.
Eagle Eyes: On level Six, complete the game on your first try. Just focus, it isn't too hard.
Click, click, click...: Level 27, just keep at it, after a while you'll get it. Just keep working at it. If it takes more than 15 minutes, start over. keeps you fresh.
