You know that ZZ Top song "Legs"? Well Ariel the mermaid has legs now and she knows how to use them, only she forgot to specify what kind of legs she wanted so Ursula the sea witch stuck her with some sexy crab legs.
She seems to be fine with it, and Eric sees her sexy crab legs as a form of life insurance, guaranteeing he'll have a crab leg buffet waiting for him when Ariel dies.
But, as this Electric Bunny Comics strip shows, the townies aren't as open-minded as Eric so they ran poor Ariel out of town. Maybe if Eric had told them there was a possibility of all-you-can-eat crab legs they would have let her stick around...
