JUANDELACRUZ: Remember Mero the Mermaid

JUANDELACRUZ submitted:

Remember Mero the Mermaid from that Monster Musume entry in 2015? Well, if you’ve ever wondered just what those pelvic fins are for, here’s the official canon explanation. Apparently, they are used so the mermaid can move on land just like a seal…on her chest using her breasts. 

I guess I have to give them credit for attention to detail.  Is there a canon reason why she looks like a Tetris piece in the last panel too?
