How do you beat level 7 on me and the key 3?

Answer 1

Grab the wall stripe at the far left: the key is behind it.

Answer 2

Put both penguins in a circle.

Using your arrow keys,

1) press down until both are at the bottom

2) press right until one goes into the slot

2) press up and the free one goes to the top of the screen

3) press left and both go to the left wall

4) press right and slide them into the orange circles

Answer 3

Click the left penguin, then the right penguin, and repeat until all 5 of the lower ones are up. The penguin with the key rises in the middle.
