i dont think many of you will care, but here's an explanation for the underwater amogus. this was my clip, and it came completely legit from my survival world due to a glitch. i created the world around january in version 1.0, starting an "evolution" play through, where i would play through the game, changing versions every so often, i never saw this abomination form, but my best guess it that sand at the lake bottom fell causing air pockets to form and result in the monstrosity that you saw
