Secret Bananas and Coconut plants dont add any game completion percentage but they have a hidden effect. You dont need to get these plants in order, except the first one (which spawns the others in the game).
- Specter Land - Look for the building with Specters picture in the long hallway near the upper level door. There should be a red pot inside that space building.
- Specters Factory (present time) - Right at the pipes needed to be crossed, get to the other side. The plant should be floating over the lava.
- Medieval Mayhem Crumbling Castle - Look for the platform you get to by jumping off the top of the castle, and heading towards the back and left.
- New Freezeland Snowy Mammoth - Go find the large machine in this area. The plant can be found on the pipe nearby.
- Oceana - Dexters Island - Locate the turtle held in the water. The plant will be nearby.
- Mysterious Age - Thick Jungle - Go to the tunnel just ahead of the spot where you need to use the Sky Flyer (to move on). Open the gate there, then turn right and go through the hedge and locate the plant behind the tree.
After you get all the plants, you can make them grow by fetching those energy chips. As the plants grow in size, the plants change in size and shape and do other weird crap.
