First adding the water level + the jellyfish boss fight like CI5
Second add water plants which contains 97% water
Third adding the water shield to enter this planet this planet contains the water level
I don’t think this must be added imo. The Weakest/Strongest Link and Droid Slalom/Giant Slalom are better replacements for this. Moreover, Henpire’s technology has changed very much after CI3, so for chickens eggdrone-minefield became an obsolete thing.
