Look I am not happy that I’m writing this post but I really don’t understand why I’m seeing multiple posts about why Mermaid Man and Barnacle Boy are the same size as the residents of Bikini Bottom when they’re human beings and all the sea creatures are only supposed to be a few inches tall. Mermaid Man’s belt is a shrink ray. They did a whole episode about it. I feel like you can put two and two together without them explaining it onscreen. What you really need to be concerned about is why Pearl, a whale, is also only a few inches tall and also never needs to go up for air.
