The Laboratory
You have to go up the leftmost ladder to get to every nugget and then exit to the next level.  Come across from the right to collect the top centre nugget.

Get past enemies on the 'bunsen burner' by killing them on the right of it, by dropping through the middle of it when they are nearly touching you and will fall after you OR by jumping left over their heads before they get to the top of the burner.
