Where are the pants in home sheep home 2

I only know four.
Level 3 : The pants are inside the trunk, the only way to get is using Shaun, because Shaun can jump higher.
Level 5: Pass all the three sheep to to other side, but leave Shaun fall after the last chimney, and enter in the window to get the pants, then you only have to jump three times to go to the other level.
Level 6: The pants are in the window again, so pick Timmy and jump on the balloons in a way that makes Timmy enter into the windows.
Level 8: The pants are behind the two boxes in the high-left side of the screen, you can pick up Shaun and jump to it, will not affect your way back

I think the last is hidden in level seven, but I could not find.
