Infragreen Goggles

This upgrade allows you to both see through green clouds and they also increase the range of your goggles so you don't have to be inside clouds to see through them.

You must have the Infrablue Goggles in order to get this upgrade. You may find it on level 55. You must stand in the yellow flower until its color completely fades. This is difficult since it will damage you more and more the longer you stand in it.

After that flower turns purple you can then teleport to a new level with this upgrade by entering the red flower.
