I was really trying hard to get the movie Mega Shark vs Giant Octopus out of my head. I guess the only way I could was to come up with something satirical like this.
The scene and execution are pretty vanilla, with the exception of the bubbles/foam which were a huge time killer. I figured out a good scheme for doing it if I ever wanted to again... but I swear I hope it never comes to that, haha. I hope you enjoy the bath!
