Giant Gadon is a boss in Dave the Diver.
It makes its appearance during Find the Glacial Passage Exit in Chapter 5 where, on being accidentally woken up by Dave, will chase after the scuba diver. Eventually it meets its end when Dave and Suwam manage to crush it under a pile of boulders.
Combat tactics[]
Unlike other bosses where you have to fight and damage them, this one you can only swim away from. As soon as the chase starts and until it ends, you'll have to navigate around stalactites and stalagmites, dodge falling ice chunks, as well as attacks from the Giant Gadon, like it trying to grab Dave. There are a few small cutscenes throughout the chase in each new section, as well as a few quick time events. Note if you are caught by the monster, you'll restart at the beginning of that segment (usually when the previous cutscene occurred).
