Green sticky blocks are varying shades of green, hence the name, and occur in many sizes. They are mainly translucent, although they have a green outer layer that is opaque. If Norman Noggin tries to jump while standing on sticky green blocks, a green stringy goo will be seen sticking to his feet and pulling him back down.
Green sticky blocks are similar to pink checkered blocks in that they can be walked on and do not harm the player. However, the main difference is that green blocks can not be jumped off of. If Norman Noggin tries to jump off of a green block by pressing , he will jump for a short distance and be pulled back. Also, many enemies and hazards can be found on pink checkered blocks, so the player must be careful not to lead Norman Noggin into any of them.
