Well, everyone knows that the green chu creature was taken out of the game because they took the magic meter out. Well, when you kill a chu creature they turn into a pile of jelly equal to the color that they were. The red chu jelly is the equivalent to a red potion, and blue jelly a blue potion and so on and so forth. However, because the magic meter was taken out, the green chu was also taken out, along with the green chu jelly.
However, if you have the original print run of Twilight Princess (oply for Wii, trust me I tried), the green chu creature still appears in one place, and yes he drops green chu jelly. On floor 19 in the Cave of Ordeals, progress slowly, there are about 30 chu creatures resting in the ceieling, and they will fall once you approach underneith them. This is the only place that every color of chu appears, red, purple, blue, yellow, and the elusive golden chu. However, every chu has the ability to morph into another color when it combines with another chu, every combination will get you a purple chu jelly, except if you can get the blue and yellow to morph together, the repectively morph into a green one. Progress slowly, (I wish I had some way to prove it, but seriously take it slowly, kill every chu that drops except for the yellow and blue, lure them together to get a green).
When you collect the jelly, a text box appears, but no words print out saying that you have the jelly. If you click on info in your inventory, it says nothing, there is just green chu jelly in a bottle in your inventory, and when you put the cursor on it, it just says Green Chu Jelly. When you drink it, it does absolutely nothing. I went out and caught it and keep it in my inventory, it looks neat.
