It quite interesting that after so much time we didn't saw any patches\fixes on these major problems with above mentioned achievements. Wouldn't it be easy just to use same checks as for "Rock 'n' Roll" ? Because I recently checked a lot of post about possible ways to get it, also on other platforms, yet any of them worked for me even "cheese" ones. As for jelly fish it kinda rude to no fix shorterms, because u can meet a lot of them in non suspicious at all places, or even not redered proparly, so it voids the 3 achievements just because.
