If there's a better metaphor for 2023 I don't know what it would be. Something involving submersibles... Yeah, no, I'm going to go with Barbenheimer.
Was there a Barbie submersible bath tub toy? If not, they should make one. They can make it a companion to the Barbie yacht. You can even put a back story that she bought it from an auction from a sanctioned russian oligarch
I doubt this is what you meant but what came to mind was Super Slide Kelly! Barbie wasn’t necessarily my first choice toy (I usually defaulted to LEGO), but I vividly remember Kelly because my mom bought her for me when I was six years old and sick with the chicken pox. She was my one bright spot from that awful week. She had a bitchin slide that (I think?) suction-cupped to the wall and you could make her slide into the tub.
